RH Negative Blood Type and Rhogam Shot

I was thinking earlier today that I should do a post about what it means to have a negative blood type during pregnancy and what the rhogam shot does. I considered doing this post because it isn’t well known and it added to my confusion and grief during a traumatic time in my life. If only someone had taken the time to explain it to me back then! But you know what? Even people in the medical community don’t know what it’s all about! I majorly questioned the nurse who gave me the shot while I was miscarrying, but my questions went way beyond her scope of understanding to the point where she just said “I don’t know, I didn’t major in obstetrics.” I called the 1-800 Telehealth Ontario phone# and questioned them. The nurse there had to pull out her manual and could not answer my questions using all of the resources available to her. I asked my friend, a nursing student, who went through all of her nursing books as well as the medical sources available to her as a med student that aren’t available to the general public. My questions went beyond the answers. I have read up on it like crazy, as best I could. I feel like I know so much more about it than many people in the medical community and definitely more than the general public – who are completely oblivious to the issue, unless they have a negative blood type and have been pregnant before.

RH- blood does not like RH+ blood. If RH- blood comes in contact with enough RH+ blood, the RH- blood will begin producing antibodies to fight off the RH+ blood because it sees it as a foreign and dangerous invader. It is a natural response like an immunity response. If an RH- woman is pregnant with an RH- baby, everything is wonderful and honky dory. If both the mother and father are RH-, then the baby will also be RH-, however, doctors may very well treat the pregnancy with the assumption that the baby is RH+ anyway, on the chance that the mother may have been messing around, etc. The doctors don’t want to take the risk that the mother is lying or withholding information. If the father is RH+, there is a good chance the baby will be RH+ as well because RH- is a recessive gene, meaning usually the RH+ wins over the RH-. I could go into this more if you are interested, but like the docs will do, I will just assume the baby will be RH+. Better safe than sorry. When an RH- woman is pregnant with an RH+ baby, things become interesting. The first pregnancy is generally considered safe. During a healthy pregnancy, the RH- blood never meets up with the baby’s RH+ blood. It only happens if something goes wrong, and it happens during childbirth. Once the RH- blood meets with RH+ blood, it begins producing antibodies within the next 72 hours. These antibodies will continue to reproduce. Once the RH- blood begins producing the antibodies, there is no going back. The antibodies are there for life. As I said, the first pregnancy is generally safe. The antibodies are unlikely to damage the current baby that initiated the production of antibodies. The future pregnancies are the ones that are in danger. The antibodies can “attack” future babies who have RH+ blood types. There are different effects on a large spectrum. At it’s worst, the antibodies can kill a future baby. At it’s best, there are no effects to the future baby whatsoever. A common effect is jaundice. Jaundice is VERY common in new borns and is usually treatable. Unfortunately in the case of RH- antibodies induced jaundice, it could potentially be a very bad case of jaundice to the point where blood transfusions are necessary. I’ve even read of cases where blood transfusions were performed within the womb! (successfully). I hope you haven’t stopped reading yet because there is good news! And lots more good news then you have probably ever heard regarding this whole scary negative blood type thing!
First of all, there is the rhogam shot. Usually in the USA and Canada they give a rhogam shot at 21 weeks of pregnancy. This is because before that time, the risk of the RH- blood coming into contact with the RH+ before 21 weeks, is slim. As I said, unless something happens, the chances of the blood coming into contact during a healthy pregnancy is low. The rhogam shot puts antibodies into your blood stream letting the RH- blood know there is no need to produce antibodies, because they are already there (from the shot). The thing is though, the antibodies in the rhogam shot are basically duds. The antibodies in the rhogam will not harm your baby. After giving birth, the rhogam shot is given again within 72 hours (likely within 24 hours). If there is any sign of trauma within the pregnancy, the rhogam shot is given as a precaution. If there is a miscarriage or a threatened miscarriage, the rhogam shot is given. When it is an early miscarriage, the shot is given as a precaution. From what I have read, it is given during an early miscarriage based on the theory that the blood interacted. I have not read anything that demonstrated to me that an early miscarriage without the shot has actually caused the antibodies to begin production. This is good news because many early miscarriages aren’t even known to have taken place! It is actually pretty common for a woman to not know she is pregnant until she miscarries, or even when she does miscarry that early, she just thinks it’s an extra bad period.
When I miscarried the first time, I was only about 6.5 weeks. The hospital gave me the shot, as I explained. What I haven’t mentioned yet is that with this current miscarriage, my OBGYN did NOT give me the shot. I asked him about it, and he affirmed what I had concluded from my own research, that at such an early stage, the baby is MUCH too small to even have enough blood to interact with my blood. I don’t know how much blood needs to interact but it must be more than a tiny droplet or we would be more concerned about building up these antibodies through regular accidents you might come into contact with throughout your life (or through the old childhood practice of blood brothers/sisters). My OBGYN knew that the gestational sac was only 2mm in size, and he told me that it would not have enough material to it to cause an issue. After all of research I have done on my own, I was pleased with his response. And I did NOT get the rhogam shot this time around.
Don’t go away yet, I have more info!
After my first miscarriage, I asked my family doctor about my risks of not having got the shot soon enough or if the shot didn’t work, or if I should have got a second one after the miscarriage, etc. My family doc sent me for blood tests to tell us how much antibody was showing up in my blood. This was a month or two after the miscarriage and the shot at this point. The blood tests came back showing that there were antibodies in my blood. But there was no way to know if they were from the shot or if my body had produced them, so another blood test was necessary. The second test should have shown the level decreasing if the antibodies were just from the shot, not my own blood. Well, the number hadn’t changed at all. Months later I did the blood tests again and the antibodies were completely gone. So although it was weird the way they had stayed in my system, I know they did go away eventually so my RH- blood was still safe and clean from the scary antibodies.
So this mysterious rhogam shot… it has some controversy surrounding it. Up until a few years ago, it was common for the rhogam shot to have thermisol in it (aka, that mercury preservative that people are afraid of in the vaccines). Perhaps our adult bodies can handle that amount of thermisol, but can our little unborn babies handle that amount? That’s a fear out there. You have the right to ask for mercury free rhogam. From what I have read, for the last few years, the rhogam shots in the USA are mercury free. But it doesn’t hurt to ask anyway, if it is a concern for you. I haven’t found any info on whether Canada’s rhogam shots are mercury free. And I haven’t asked anyone in the medical field here. I will ask when the day comes again that I must face the rhogam shot in my butt. There are some stats out there that are really really scary. They relate the occurrence of autism in children born to an RH- mother who had the rhogam shot. Scary. Look into it yourself. Who knows how thorough the research was that put together those stats. I have read that in some European countries, they do not give the rhogam shot at all during pregnancy unless there is trauma that could increase the risks of blood interaction (such as a car accident). In those countries, they give the rhogam shot after delivery. Some people in North America request this as well.
What are the risks of blood interaction anyway? Slim during a healthy pregnancy. During delivery, you are almost guaranteed to have blood interaction. I think it is like 95% likely that the blood will interact during childbirth. That percent is a little lower in home births, however. This is due to it being a more relaxed environment at home then often found at the hospital. It isn’t low enough to convince me to forgo the shot, whether I did a home birth or not (although it is an argument for home birth…).

    Fascinating subject – thank you for sharing! I was clearly deficient in my knowledge about RH- / RH+ shots, etc. :)

  2. Christine says:

    Thank you for explaining this

  3. erica selby says:

    Im not sure if I am RH- but my husband is O- and I’m O+ is it impossible for us to concieve a baby? I’ve been with him for 3 yrs and I’ve miscarried but never tld my mother. She told me she needed the rhogam shot to have me and my brother. If I’ve waited 2 yrs and possiblely had other miscarriages is it too late for me toget it?

  4. Amanda says:

    If you are o+ and your husband is O-, then there is no problem. As long as your blood type has a + after it, you are safe no matter what his blood type is. If your mom needed rhogam then your mom had a – after her blood type.
    Just as a further note, your children could have either – or + blood types because your mom is a negative she has passed the negative gene to you and you are just a “carrier” of it. Your children might be either way. But it doesn’t matter as far as the safety of your pregnancy goes. As long as the pregnant woman is a positive, she has nothing to worry about no matter what her husband or children are. As long as you have the + after your bloodtype, you do not need the rhogam shot at all. You only need to worry of the pregnant woman has a – after her blood type.

  5. Kim says:

    Both my hubby and I are O- so thankfully we’ve never had to worry about the shots. My mother was O- as well and my dad + so she needed the shots.

  6. Shema says:

    I am also RH- and I’ve had my first child, which is +. I fought the midwives in not taking the rhogam during the pregnancy. I took it after I had the baby because my research showed me the same things. I’m now pregnant with my second and the doctor is pressuring me to take it. Like you said it’s too much mercury for the baby. Also they say it’s most effective within the 72 hours you’ve had the trauma. I was debating taking it,(having doubts) but my doctor told me a statistic, that (can’t remember the figure) something like 60-90 thousand women have taken it and they’ve had no side effects.But my question is this? How many women have been RH- and had healthy babies with out the shot? (Assuming the rest of the women in the world) At the end of the day I have to keep my faith that it is all in Gods hands.

  7. Amanda says:

    Thanks for the comment! I’m glad to “meet” someone who did similar research and found similar results. I am nervous about making that decision myself some day. There is going to be a LOT of pressure to get the shot during the pregnancy. And if something went wrong, you’d be so angry with yourself. ACK! I commend you for staying strong and true to your convictions.

  8. Leona says:

    I am in Ontario, Canada … I have read that WinRho is preseritive and mercury free — call Cangene in Winnipeg, MB, Canada 1-877-226-4363.

    I am still researching this product. I am considering having the shot only after my labour. Hard choices!

  9. Amanda says:

    thanks for the info!

  10. Laura says:

    I am o- and my husband is o+, my first pregnancy ended in a miscarriage, and they never checked my blood type so I didn’t receive the shot. My second pregnancy my obgyn did check and I did receive the shot at 28 week, and my O- son was born so no shot after delivery. My third pregnancy same story only my O+ daughter was born so yes shot after delivery. Surprise 4th pregnancy same story and then my O- son was born so again no shot after delivery. Now both of the O- boys are perfect, no problems what so ever, but my O+ daughter had delayed speech and learning disabilities. I was wondering if it wasn’t so much the shot causing problems as it was the difference in the RH factors.

  11. Amanda says:

    that’s fascinating. I wonder.

  12. Kailey says:

    I am 6 weeks along and started bleeding heavily. I went to the doctor and they told me that I am rh negative. I had to get the rhogam shot and I was wondering if this could actually help the pregnancy? Could it give my baby a chance?

  13. Amanda says:

    Hi Kailey,
    I’m so sorry you are going through this scary time. Unfortunately I don’t think the rhogam shot you just had will help your current pregnancy, but it certainly will help towards your future pregnancies (but I’m not a doctor so I might be wrong about it’s effect on your current one). That being said, sometimes there is bleeding in a pregnancy that ends up going to a healthy full term so I certainly hope that is the case for you. If it does result in miscarriage, and I know that is your fear right now, I am terribly sorry for your loss.

  14. sarah says:

    Thank you so much for this. I have searched and searched for info. Here’s my question: (I understand you are not a doctor, but I am hoping you will be able to let me know what you think).

    I was pregnant with my 1st child, and miscarried at 5 or 6 weeks (blighted ovum). I went to the emerg, they did bloodwork, said I did not need the WinRho b/c I am +. Turns out I am actually – (how they screwed this up is beyond me). Anyway … I guess it is too late now for the WinRho that has to be given within 72 hours – do you think there is still a possibility for me to have kids, or are my chances now basically over?


  15. Amanda says:

    First of all, I’m sorry for your loss.
    and no your chances aren’t over. I agree it is crazy that the hospital missed out on your blood type! but what’s past is past, let’s deal with the hear and now. Since you miscarried at just 5 or 6 weeks, I don’t believe that you would have had enough of the baby material there for it to interact with your blood negatively anyway. When I had my second miscarriage my OBGYN/fertility specialist and I agreed that I did not need the shot and I was around 6 weeks give or take. You can totally get a blood test to find out if your blood did actually start producing the antibodies that could affect your future pregnancies! I had that blood test a couple times after my first miscarriage, actually. I can’t remember what it is called but it tests for RH Antibodies. I don’t know where you are located but in Canada the blood test for this is absolutely free and easy. I have no idea what it would cost if you are in the US. Even if your body has created the antibodies, it does not necessarily mean you won’t be able to have a healthy future pregnancy. Talk to your OBGYN about the risks. I feel confident that your blood type will not harm your next pregnancy.

  16. shamirah says:

    i am rh- and i had my first baby last year i got the shot after the birth now im on baby number two im not sure if im going to have the shot this time around do you guys think im takeing a big risk this time

  17. Amanda says:

    I don’t really know. There are a few things you need to think about. Do you plan to have more children after this? If this is your last child, then it doesn’t matter whether you develop the RH antibodies after giving birth to this child. Otherwise, you need to do some research and soul searching before you decide whether or not to get the shot this time around. I am undecided on what I will do when I need to make such a decision.

  18. Danielle says:

    Wow, this was all so helpful. I miscarried 6 months ago in my 6th week. I am RH negative blood but had no knowledge of any of the risk of having this blood type until now. I did not recieve a rhogam shot after my miscarrage. I am now 5 weeks pregnant and am worried because I didn’t get the shot. After reading this blog I am alittle at ease with your research. I hope this turns out well.

  19. ina says:


    I am RH- and I just do not know what to do: to take the shot or not because I read a lot about people RH- who took the shot during pregnancy and later their kids were autistic. My doctor did not check my blood for antibodies at this point 28 weeks. She only said that is routinely given to RH- mothers and it is very important to take it.
    I am confused and I tend to wait until after I give birth because there are chances that the baby has RH- blood and there would be no point to have the shot during pregnancy (especially when it is not 100% sure that they are 100% mercury free).
    I do not know if I take the right decision but it would be even harder to know that I took a decision that would harm my baby.
    Anyway I am still very stressed about this…
    I live in BC Canada and I wonder if I ask for a blood test to check my antibodies would my dr order one for me or can I do it somewhere and pay for it?

  20. Asgsg says:

    I got a shot at 11 weeks.. now scared my baby will be autistic.. god !!! hear so many rhogam horror stories.. i regret taking the shot i had “some”spotting.. and they gave me..

  21. Amanda says:

    I’m glad I was of some help to you to reassure and ease your mind. I wish you all the best!

  22. Amanda says:

    I think the chances are slim enough that you can feel relatively at ease. When you consider that most RH- women just get the shot because the doctor told them too and most women turn out fine… you will likely be fine. I know there is that little voice that says “but it isn’t ALWAYS fine…”. but keep your chin up because you are strong enough to handle whatever happens (and I’m fairly certain you and baby will be ok).

  23. Amanda says:

    well my doctor has no problems doing any tests I ask. I think he figures it is better to do the test and ease my mind then leave me stressing about it when a simple test will make me feel better. but not all doctors are like that.
    I am still undecided as to whether I will ever get the rhogam shot while pregnant again. I’m very undecided.

  24. shade says:

    My baby heart beat stopped at 7 week. 3days so I did an evacuation around 11 week when I found out am o- but did not take the shot, now am 5 week pregnant what are my chances I really need this baby

  25. Amanda says:

    I think your chances are pretty good but I think for your piece of mind, you should ask a doc to do an RH antibody blood test. It’s just a simply blood test and it will tell the doctor if your body has created the antibodies that can be dangerous for the baby you are carrying.

  26. Jennifer says:

    I am 25 weeks pregnant with my 2nd & B-. I had the shot when I was pregnant with my first son because we didn’t know my DH’s blood type but it turned out my son was neg as well so it wasn’t really needed. Since then my DH went & gave blood to find out his blood type & we found out he is O+ so we have a chance of having a + child. Now our dilema is, should I do the shot again, we don’t plan on having anymore kids after this.

    But even if we decide not to have anymore kids, what if something happens to this baby & we change our minds, what if we get pregnant by accident? That is what we are fighting with now. I am 35 years old & don’t want to have any more children at my age.

    I spoke to my midwife (I am in Ontario, Canada) & she said lots of women don’t get the shot because of personal or religeous beliefs, Jehovah’s never get it because it is a blood product. I am going to question whether I can skip the 28 week shot (that’s when it’s done here in Ontario routinely) & get it at birth if the baby is +.

    It’s a hard decision to decide whether or not to do things for our children when we aren’t sure of the safety. My son reacted to his 6 month vaccines & I now have a new outlook on injecting foreign material into me while I’m pregnant.

  27. Amanda says:

    I’m no doctor so I don’t want to necessarily advise you but I feel like if I myself were in your position with all of the details you’ve mentioned, I would consider skipping the 28 week shot and just get the shot immediately after giving birth (if at that point the baby turns out to have a positive blood type, I think your chances of that happening in your case are 50/50).

  28. Bonnie says:

    I have A- and my husband had B+ I had to have the shot after my daughter which was a C-section and 3 years later I had a son by C-section. I was givin the shot after having him but the Dr also said I could not risk having anymore children so he did a tubal. Both children are healty that was in 1978 and 1981.

  29. Amanda says:

    wow, I wonder if the same scenario happened today if they would have insisted on a tubal.

  30. Brandy S says:

    Thanks for posting this conversation – very interesting! I too had a bizarre experience with blood types… I was on the delivery table when someone asked me if I knew I was rH negative and if I had Rhogam. I DIDN’T realize I was neg and hadn’t had the shot. Most of the information went over my head at the time but was assured all was fine. I was NOT given the shot after the birth, so I am led to assume that my daughter was also rH negative.

    I’m now pregnant with my second child and facing the ‘get the shot / don’t get the shot’ question…

    Do I understand this all accurately? If my first child IS in fact negative, then there isn’t any additional risk to THIS second baby because I’ve not had the antibodies triggered?

    I should theoretically be fine to deliver this child without taking the shot and IF baby #2 is positive, THEN I get the shot post-delivery.

    Do I have this accurately?

  31. Elizabeth says:

    Please,i am a 26year old lady,i had my second miscarriage three months ago. After reading this post,i got scared. Do you think it is too late for me to take the Rhogam shot? Am scared of loosing my next pregnancy. My obgyn did not test my blood during the first pregnancy and am sure that is were my problem comes from. Pls answer this,am really distress

  32. Helen says:

    I have A- and my husband has o+.I miscarried 2 weeks ago in my 8th weeks. After that I wanted to get sot Rhogam but Dr in hospital sayed: you don’t need it beacuse it’s early miscaraige.Now I am worried abut future baby.I think now it’s late for injection.

  33. Blair says:

    thank you for the great information, I was wondering if you have any information about getting the shot over 10 years ago, after a termination. I am Rh- and now I am pregnant and don’t know what the chances are that (1) my baby is okay and (2) what are the chances that my baby will have autism?!??! my doctor doesn’t seem too concerned but I am?! any information will be welcomed!

  34. Amanda says:

    if you had the shot after the termination 10 years ago, you and your current baby are likely to be just fine. :)
    the shot you had 10 years ago will NOT have any negative effect on your current baby. shots you have during this pregnancy may or may not have a negative effect but most doctors would say no negative effect. I am skeptical of any research regarding the RH shot during pregnancy and autism (or other possible links). I feel like currently the research is all so biased I just don’t know if any of it can be believed. That said, even if there is a link, I don’t think the rate of it is high enough to warrant anxiety over it during your pregnancy. take care of yourself and be the best mama you can be.

  35. Amanda says:

    sorry I didn’t reply sooner. yes, you are now too late for the injection. most docs give the shot even if it is really really early. I researched it on my own and confirmed with my own fertility specialist that early term miscarriages are HIGHLY UNLIKELY to cause the antibodies you don’t want. I believe that so much so that with my last miscarriage I chose not to have the rhogam shot and was fully supported by my fertility specialist in that decision.
    I wish you the best of luck with future babies!!! by the way, if you are still concerned and want to ease your anxiety, it’s a simple blood test to check for the antibodies, you can ask your doctor to have it checked for your own peace of mind. I did that myself after the first miscarriage.

  36. Amanda says:

    sorry I didn’t reply sooner. yes, you are now too late for the injection but if the miscarriage was early on you are likely fine. I researched it on my own and confirmed with my own fertility specialist that early term miscarriages are HIGHLY UNLIKELY to cause the antibodies you don’t want. I believe that so much so that with my last miscarriage I chose not to have the rhogam shot and was fully supported by my fertility specialist in that decision.
    if you are still concerned and want to ease your anxiety, it’s a simple blood test to check for the antibodies, you can ask your doctor to have it checked for your own peace of mind. I did that myself after the first miscarriage.

    I am so glad that I found this and thanks for sharing with us!
    I just recently had a misscarriage i was 5wks. And this was my first pregnancy. and when I was spotting around 4wks I went to the doctor and they told me that in early pregnancy spotting and cramping is very common and nothing to worry about. And they also told me I am O- and they gave me the rhogam shot. I’m just wondering if I got the shot late?or if i had gotten the rhogam shot earlier would I still have my baby? And when I miscarried the doctor gave me another rhogam shot. And just really confused because my sister also is O- and she only got one rhogam shot and she delivered a healthy baby boy and now my nephew is 6 yrs old and hyper as can be and just full of happiness and lots of energy. I just wonder why I lost my baby even though I still got the rhogam shot. It just confuses me and gets me a little angry/upset. What are my chances of having another misscarriage if I had 2 rhogam shots?

  38. Amanda says:

    I’m sorry for your loss.
    The rhogam shot was given to you to protect future babies. It is somewhat irrelevant for the current pregnancy. It wouldn’t have saved or harmed the recent pregnancy. What the shot does is provide sort of fake antibodies so that your own body doesn’t feel the need to create the real antibodies when your O- blood meets the baby’s O+ blood during miscarriage. The real antibodies, if present, can potentially harm future babies because the antibodies fight off O+ blood seeing it as a foreign substance. just potentially harmful to future babies. the antibodies may or may not harm future babies. doctors just want to be safe and stop your body from making those antibodies. Rest assured that the rhogam shot was given to you as protection for your future babies. It made no difference either way with the baby you were pregnant with at the time. It isn’t unusual for doctors to give the shot while you are pregnant then again immediately after miscarriage or birth. In my opinion (and I’m no expert), your miscarriage was so early that even if you didn’t get the rhogam shot at all, your body wouldn’t encounter enough of the baby’s O+ blood to even know to create antibodies. The double dose of the rhogam you got will not harm future pregnancies.
    I know first hand that miscarriages are physically and emotionally painful as well as scary. You may worry a lot about future pregnancies – that’s totally normal. But it’s also good to keep in mind that miscarriages are extremely common and are most often during the first few weeks of pregnancy, as yours was. Just because you have had one miscarriage does not mean you will have more. They are so common. They happen a lot more often than we know because sometimes women are pregnant and miscarry in the first 6 weeks without ever even realizing they were pregnant. Generally it means something just wasn’t quite right. It usually has nothing to do with anything you did or didn’t do. It’s natural to ask yourself if you should have or could have done something different but honestly, most of the time early miscarriages would happen no matter how perfect the mom is.
    I wish you all the best.

  39. my wife is b negative and i am o positive so iam facing such a problem that is mention below

    Hello, my question is this, after I had my son 14 years ago I don’t remember getting my rogham shot. I am rh-, and I just had a miscarriage at 10 1/2 weeks. 1. Could I have had the antibodies after these 14 years that caused the miscarriage?
    My Doctor did do my prenatal blood work at 5 weeks, would the have tested for an over abundance of antibodies then 2. or is it a special test I need to get done?
    One more question if I am blood the A- and rh- and my husband is any type of – A- or B- or O- or AB- 3.is there risk of developing the antibodies if the blood mixes in a future pregnancy or would it only be a problem if his blood type is any kind of positive? I look forward to your reply and thank you for all of the valuable information.

  41. Ana says:

    Hi, I just want to say thank you for taking the time to write this article for us women that are rh-. I found out that I was expecting last sunday after a postive HPT. Monday, I started spotting so I went to see a doctor. They confirmed that I was pregnant (5-6 weeks) told me not to worry about the spotting because it sometime is normal and my cervix was closed. They did lab work to check my HGG and confirmed how far my pregnancy was. However, the spotting turned until bleeding, my HCG was only 420 and they did an ultrasound and didnt found any pregnancy signs. She rechecked my HCG and it came back 406 =( my doctor told me that my body is getting ready to miscarry. On Friday Pm, the doctor realized that I was RH- and sent me to the hospital to get the RHogam shot. However, the hospital only does the shot on weekday for outpatients, hence I now have to wait until tomorrow Monday to get it. Now, I am bleeding more and becoming more nervous that I am going to get it too late and ruin my fetility. But, after reading this article I feel more at ease. Hoping everything will go well the next time, I dont think I will tolerate losing another pregnancy, being a mommy is my ultimate desire in life. Thanks again.

    I’m glad I was able to bring some peace of mind to you in this awful situation. I’m sorry you have lost your pregnancy. I know how that feels and it is terrible. It’s taken me a couple years to get to a point where I’d risk a third miscarriage to try to have a baby again.

    Am samira from Ghana and am 21weeks pregnant. Am O negative and my husband is O positive,i’ve heard about the rhogam but very afraid of the autisim aspect because 2 of my cousins in Europe are autisim but dont know the blond type of both parents. What should i do now am really scared or should i take it after delivery?

    I have looked at so many websites for information on this topic and this is the only one that has really helped me so thank you! Also I was wondering if I miscarried at 6 and a half weeks and did not receive the shot should I be concerned about my next pregnancy? They “tested” my blood with only a finger stick and said ” looks like you’re negative, oh no wait I don’t think so. No I don’t think you are” which didn’t reassure me at all especially when I already thought I was a rh negative blood type. It has been 4 days since my miscarriage, so the 72 hours I read about is gone. Do I need to see a doctor??

    I had my rhogam when I was 7 months pregnant. Everything was fine until my baby was born. He had a severe case of jaundice. He was close to the point of going death. We had to go back to the hospital every day for a whole week until the pediatrician was able to control it. But besides that my baby is very healthy and extremely smart. He is now 3.

    It blows me away how little medical professionals know about this. I found out I was rh- about 9 years ago, but nobody could really tell me anything. I didn’t understand it until I became a medical student.
    Thank you for putting this up. It shouldn’t take becoming a medical student to understand your own condition. I have learned even more which takes a huge weight off my chest. This is a great resource for the people, and has helped greatly.
