Rhesus Negative Question: Both me and my DP are Rhesus Negative, does that mean that our baby can only be Rhesus Negative?

[misselliemae]

Both me and my DP are Rhesus Negative. I am A Negative and he is O Negative. Does anyone know if that means that our baby will be also Rhesus Negative? I would prefer to avoid Anti-D in pregnancy if possible because I am concerned that it is a blood product. My midwife didn't know if us both being negative would mean our baby also would be. I thought it did mean that he/she could only be negative. If so, there would be no need for Anti-D. However, I don't want to risk the baby's or any future babies health. So am v confused. Any advice would be really appreciated. Thanks v much. Also does anyone know if there is a blood test to test the baby's blood type while you are pregnant. I thought there was, but my midwife said there was not one yet? Thanks again!

'hope this helps'

look under the heading: Who needs to take Rh immunoglobulin?

I would have thought that as RHnegative is the recessive if both parents are negative then baby will be too. In your position I wouldn't have Anti D. However DH and DD are both RHpositive so I've no real choice.

You won't need Anti-D as your partner is Rhesus negative as well. You only need it if the baby's father is positive as then the baby might be positive.

They don't usually test the baby's blood in pregnancy. It would be very invasive and carry risks I imagine.

There is only risk if you and your parnter nave different results...so you should be fine, and won't need the Anti-D.
I asked midwife about this very probability.
She told me that before deciding on whether to have the Anti-D, I could have DH tested first, and if we were both negative, it wasn't necessary.

Hello,

RH D negative is recessive, therefore your baby can't be rhesus positive.
(It might just be possible for some sort of genetic crossing over event to occur that would allow rhesus positive, I'm not sure but if so this would be very very unlikely).

There is a tiny tiny possibility of a Rh +ve baby from Rh -ve parents as I understand it though I wasn't able to find any conclusive evidence. But it's really so small a risk that I personally thought it was worth taking, given the risk of blood products. I was in your position and decided against it. They insisted on doing a blood test to confirm dh was -ve and even then I got some veiled warnings about how I needed to be sure he was the father .

There's quite a lot of discussion about this on this thread

Thanks very much for all your posts - really helpful. Based on what you say, think i probably won't have the Anti-D, but may try to do a bit more research into it. Any other experiences of this also appreciated. Thanks again.

DH and I are in the same position. I had nti-D woth my first pregnancy because the midwife said she couldn't take my word for it that DH was the baby's father. Anyway... I didn't have it with my second pregnancy.

Thanks v much! Did your first DC turn out to be negative too?
