Rhesus Negative and Anti D question

10 replies

I didn't have anti D after the birth of my last child 10 years ago because I thought I didn't want any more.

I had a chemical pregnancy last year - is it possible that I won't be able to conceive without looking at antibodies?

Obviously chemical pregnancies are quite common anyway but I'm just wondering because a midwife told me if you're rhesus negative and don't have anti D you'll keep having miscarriages.

I'm rhesus negative too. I don't think it would prevent you conceiving but it might make you more susceptible to miscarriage.

Is the father of the child you're trying to conceive rhesus positive?

Sorry, for clarity, more likely to miscarry later in pregnancy. Worth getting medical advice - I don't want to be doom and gloom but you're better off prepared.

I'm Rh- so is my Mum and my brother. My mum had 4 kids. My understanding is it doesn't affect conception but as soon as you know you're pregnant you need to schedule the antibodies. It doesn't matter the father's blood type - as they told my mum, they can't risk that a mother may lie about the real father of their child so they'll give you the antibodies regardless!!!!

Thanks. Yeah the father was rh positive.

And your last child also rhesus +?

Yes all my kids are rhesus positive but after the first two I had anti D.

I suppose you might have had an immune response with your last child. I don't think that would affect conception though. Definitely speak to a doctor/midwife. They might be able to do stuff to help these days, or at least test you. I'm pretty sure you can still have a successful pregnancy though. Flowers

Thanks Mook. My understanding had been that an immune response tends to cause severe anaemia in an unborn baby. I'm not sure whether it affects conception. I will speak to the gp I guess. I'm 38 so obviously my chances of having a miscarriage will be higher anyway.

I didn't have my anti d after having my eldest. In my second pregnancy, I had blood tests to test my peripheral blood for babies genotype. He was rhesus positive and I had to have 2 weekly blood tests to check my antibody levels. At 21 weeks they went up to potentially dangerous levels and I began to have Middle Cerembral Artery scans on a weekly basis to check for hydrops in the baby. My levels rose again and I had to be monitored in hospital every other day and have 2 scans a week. At 33 weeks they noticed hydrops in the baby and I had to go for an inutero blood transfusion. Unfortunately they were unable to complete this and he was born that day. He was in intensive care for 17 days and in and out of hospital for a few weeks with Haemolytic Disease of the newborn. He is now 12 and fine.

My DS3 I had periphal bloods done and he was rhesus negative. This test isn't 100% though so I had weekly scans throughout my pregnancy. He was born at 39 weeks fully well and is now 8.

You will be tested for antibodies at the beginning of your pregnancy, if your DC1 was rhesus positive you have likely been sensitised anf will be closely monitored. If DC1 is rhesus negative then hopefully you will have no issues.... Take the anti d this time!! Any questions just ask. I know ALOT about this.
