Anti D antibodies question - experiences please!

[Bleepers]

I had anti-D antibodies in my blood in my first pregnancy (with an RH positive baby). It was all very stressful but everything was OK in the end.

I am now pregnant again and the midwife has just called to say that I have anti D antibodies in my blood at 9 weeks. My question is this: does anyone know if the anti D antibodies hang around? (i.e. could the antibodies this time around be leftover from the first pregnancy)

The midwife wasn't sure - she said it could be leftovers or it could be a response to the new baby but we don't now yet if the new baby is positive or negative.

I hope this makes sense - I appreciate that most people don't have direct experience of this but if you do, please could you share as I'm feeling very stressed out and can't find anything online. Thank you.

Hmm I was injected with Anti D after each pregnancy to protect future babies so think you’re supposed to have Them in your blood
Perhaps ask your midwife for more information

I had anti D but it failed so I'm in the position of now producing anti D antibodies and the shot cant help with that.

It makes you very high risk if you already have the antibodies. They will monitor you closely and give you the antiD injections more often than a 1st pregnancy.

I'm Rh- but my husband is too so I only have the antiD at 28 weeks. Impossible for us to have a Rh+ baby but they insist on the one just incase.

I had anti D after the first baby and it didn't work(20 years ago.) I was told that it doesn't for 1-2% of women. Antibodies were detected at about 34 weeks (routine appointment.) My baby was induced 2 weeks early and was poorly. She soon recovered and is about to do her A levels. I would ask your midwife for more info. Try not to worry xx

They will have persisted from first pregnancy and will never go away. They often boost with each pregnancy and so finding them earlier or higher is typical. You will probably be referred to a fetal medicine unit for careful monitoring during pregnancy. Am sorry, must be very stressful.

@Chelyanne I think they do it because of the risk of non-paternity!

I know they do, I just find it funny. Hubby is military so "are you sure it's mine" is always joked about lol.

@crossstitchingnana thank you very much for your message. Was your daughter your second?

They don't know how or why I had the antibodies in my first pregnancy but the levels were quite high by the end although the baby was fine. With each subsequent pregnancy it gets more severe though which is what's worrying me.

They've tested DH and confirmed that because of his blood type we have a 50% chance of an RH negative baby each time.

@apandemicyousay thank you, this is exactly what I wanted to know.

Due to my husband's blood type, there is a 50% chance that any baby we have will be negative. That's why I was wondering whether the presence of the antibodies at 9 weeks this time confirmed that baby 2 will be positive (with all the complications that entails) or whether the antibodies would hang around from the first pregnancy anyway.

Does that make sense?
