Conflicting Blood Types

[deleted account] ( 12 moms have responded )

My husband's blood type is O positive, and I've been told my whole life I was A positive. A couple days ago I got a call from my doctor saying that my blood tests came back with a negative Rh factor, meaning that instead of A positive, I am A negative. This obviously conflicts with my husband's and worries me a lot because I know that if my daughter is positive and I really am negative, it could cause a lot of complications. Of course, I know that sometimes tests don't turn out right, and I also know that my mom doesn't have the greatest memory and wasn't around me for the first six years of my life (I lived with grandparents). They drew my blood again today to do another test, so I'll see if that test comes out the same. The doctor said I'd have to get a Rhogam shot if it does, and I hope that doesn't somehow hurt the baby if they ARE wrong.

My mom says that regardless, I would have miscarried long before now, being 28 weeks along. But I also researched Rh factors and what could happen, and the article I read said that complications can begin at 28 weeks.

So I'm worried, probably more than I should be. I know the results of different Rh factors between mother and child can include illness, brain damage, and death. But Julie reacts to me and my husband even in the womb. She quiets when we sing to her, pushes back against our hands, and seems to throw fits when she gets hiccups. So from that, I think she's healthy and all, but I'm still worried. I don't want to have gone full term only to give birth to a stillborn baby. I don't think I could handle that, especially since we consider her a miracle as I wasn't even supposed to get pregnant.

So...thoughts? Advice? Anyone have this happen to them?

I had to get the shot with both my kids because I am Rh negative... this means both my kids have positive blood type and I have negative. it really is no big deal- 2 shots (once around 28wks and the other after you deliever) as long as next wk they let you know everything will be ok. if ur negative then you'll get the shot.

@Maddie, no bleeding at all for me except right after I conceived, and it was barely any and I didn't know I was pregnant yet. I've heard horror stories from the MIL that she bled every time she picked something up or bent over when pregnant with my husband, but thank God that's not the case with me. I'm almost as active as I was before I got pregnant, slowing down a little because my belly's huge, and absolutely no bleeding, so I'm really happy about that.

I think I would have more complications if I had been to my OB before now, though. I'd be stressing more about the baby than I was. Before, I didn't even know she was a girl. Now that I do, and I have pictures, I'm starting to fuss over her a little more. Yay for bonding xD

I'm Rh negative and yes there can be complications...if it goes untreated. The rhogam shot is to decrease (and basically eliminate) the chances of complications. All it does it protect your baby from your blood and antibodies who might view it as a foreign body, so I don't see any reason to be scared it would do much else if you're really not Rh negative. You'll probably have one shortly after birth as well for your own health (although I believe only if your LO is Rh positive?). It really is not a big deal at all, my mom was Rh negative and has 4 perfectly healthy girls, my sister is Rh negative and has two perfectly healthy boys, I am Rh negative with a perfectly healthy girl and two more on the way. My only piece of advice, besides that it's not a big deal and nothing to worry about, is to request the shot in your butt/hip area and NOT the arm. My first shot during pregnancy was in the arm and OMFG that needle is a lot bigger than flu shot needles!!!! My second shot, post delivery the nurse told me she would NEVER do it in the arm as the needle is bigger and the tissue in your rear is more fatty than muscle.

@Jodi, my great grandma is Rh negative and has two children, but because her son is Rh positive she had a lot of problems with my grandma, who is also negative. So with her it seems like it affected her ability to have kids, but I dunno. And thank you for the advice on taking it in the hip! I don't think I could handle another needle in my arm anyway, I've had blood drawn twice in one week from the same spot and it HURTS. It's all bruised up, and I get my shot next week. So thank you so much, I will certainly tell them to stick my hip instead. :)

I had a bleed at 7weeks and they gave me a shot just to be safe.. there are really only risks if you bleed during your pregnancy, in which you just get a shot and the risks go away.. well thats my understanding anyway, i never even thought to worry about it! the less procedures you put yourself and baby through the better i reckon!! also dont read to much, its not worth stressing yourself out over! if you have regular visits with an OB or midwife then you shouldnt need to worry, they check that everythings ok! Good luck with the rest of your pregnancy! Its such an awesome reward at the end!!

@Jessica, I'm trying not to be too paranoid about this baby. I only have twelve weeks left and a lot can happen, but up until now I haven't really worried too much about her. I couldn't afford to, because I couldn't go to a doctor. I only recently got insurance and I lost my job because of my pregnancy, so I have had plenty other things to worry about. But when something comes up I read about it. I've taken very good care of myself and according to WebMD, if my baby is still moving as much after 24 weeks as she was before, she should be fine. And she is feisty! So I'm not worried as much :)

@Maddie, my mom said the same thing, that I would have miscarried long before now if it was going to affect the baby in a negative way. But I've also read that the baby's blood system is separate from the mom's, and it's only through certain procedures that the baby's blood can mix somehow with the mother's, which can cause the complications due to a different Rh factor. But I will hopefully not be having any of those procedures, because they sound damn painful, so...yeah. Haha.

Besides, one procedure, amniocentesis, involves sticking a needle through your belly to get a sample of amniotic fluid, to test for Down Syndrome and stuff. That sounds like it would hurt like hell and could hurt my baby if the doctor isn't careful. I'm not taking that risk, never, not in a million years. I'm too attached to this little monster :)

I'm RH neg and my baby was born positive, just got a shot in my bum and all is good! If the different blood types were going to affect bubs then it would have really early, like within the first weeks of conception i believe...

Well I hope all turns out. It might be a good idea to get a second opinion from another doctor. I decided not to worry even tho I still believe that I was RH negative with my son...I was told when I first got pregnant and I know that he is RH positive and we weren't the same. I would try not to worry too much. There are so many things that we are made to be afriad of for no reason at all. I am so much more paranoid this time around then I was with my son and I knew nothing when I was pregnant when my son and did all kinds of research to reassure myself. This time nothing reassures me at all. I was freaking out waiting for my test results for the...now I can't remember what it was called but that blood test for Down Syndrom and Neural tube defects. Now I am freaking out b/c I now my next test is the Gestational Diabetes test! I didn't even get the test for Down Syndrom and NTD with my son but I did this time around.

I understand completely wanting to be safe. I don't think that I could ever deal with the death of my child or have a still born baby! It would break my heart probably for good. I think that getting a second opinion is a good idea...if you like the office that you are at then I'd just seek a second opinion but if you don't care for them I'd search for another doctor. I really like the office that I am at and I don't think I'd find some where else to go...but if I was in your situation I'd seek an opinion of another doctor for sure! I'm starting to wonder if they even know ne thing at all. Ne way good Luck seriously...I hope that every thing works out and goes well for you, your husband, and your baby girl!!! We all just want to have a happy, healthy baby more then ne thing and I hope that all goes well !!!

My mom is Rh negative. All four of us kids are positive. I'm guessing that this is your first pregnancy by the way you are talking. After your daughter's birth you will recieve a shot if your daughter is Rh positive and you can after that have more children.

The miscarriages happen after the first pregnancy with an Rh positive child. For instance my SIL didn't get the shot because her daughter is also Rh negative.

Yes, the article I read said it was Rhogam. I've only had two ultrasounds, one at 11 weeks and another at 27 weeks (last week). In both she was a very active baby and they located her heartbeat very easily. I read in that article, though, that it's hard to test for antibodies, or something like that. So I don't know.

I go to the doctor again next Tuesday for another ultrasound and to test if I had prenatal diabetes (I think I was already tested and came up negative but a second one won't hurt) as well as get my Rhogam shot if my blood test comes up negative for Rh factor again. If it doesn't I'll probably have to have ANOTHER blood test or maybe I should just switch doctors, if only for a second opinion. I'm not so worried about the baby, because she's constantly moving somehow, but I'd rather be safe than sorry.

Thank you for reassuring me :)

Well when I was pregnant with my son I could have sworn I was 0- and when my son was born he was 0+ and I never got that shot. I was reading it again about it with this pregnancy and was freaking out and my dr said nope you are 0+ everything is fine! Also you don't have to worry unless your body has extra antibodies or something like that which would mean that your body was trying to fight off your babies blood...b/c if you are negative your baby could be negative too! The ROGAM I think it is called should be fine for your baby and if she is active then I wouldn't worry too much. Did your Ultrasound come out alright? As long as she is staying active and they get a heartbeat every visit you should be fine. Most women miscarry early on but not always. The real worry is if your baby is RH positive and you are RH negative. What the doctor's office needs to be testing for is antibodies in your blood...at this point in your pregnancy your baby's blood and your blood are seperate and waste is only passed between your baby and you and oxygen and nutrients and what not...ne way but you aren't sharing blood! I would talk to your doctor about all of your fears and concerns. I have a book called Your Pregnancy Week by Week. It is a great book and it talked about that a whole bunch and made me go to my doctor and ask them what was going on b/c I still believe that I am RH negative b/c that is what I was told when I became pregnant with my son! You should discuss all of your concerns with your doctor. If you are RH negative and your baby is RH positive there will be those antibodies in your blood and they are attacking your baby's blood and the ROGAM (again I THINK thats what it is called) keeps your body from doing that and is nessacary for you and your baby...they also give you that shot after birth...I can't remember why but I know that I read it in my book! Good Luck!
