I am RH- DH is +.
I've been pregnant 3 times and its not been an issue in my pregnancies or effected the pregnancy afterwards. I have a dreadful obsteric history but nothing to do with my RH- status.
Pregnancy 1: I had some light bleeding at 15 weeks and given Anti D as a precaution, then given it again after a huge hemorrhage a few days later.
My baby died the following week I was given it twice more the day of delivery and the day after.
Pregnancy 2: I had a huge bleeds at 7 and 9 weeks due to a placenta Hematoma but didn't need the Anti-D. I believe this because the placenta is fully functioning and you don't propery share a blood supply.
I had a little bleeding at 18 weeks and was given anti - just incase.
At 19 weeks when I delivered I was immediately given Anti-D.
They then did a blood test (they probably did this in first pregnancy too) and 24 hours later found that a small amount of blood had been shared between the baby and I. So I was given another Anti-D and the test was sent away for further testing to see how much blood had been shared and if I needed another.
But the machine that was to do the testing broke so I was given another later that night just in case. It turns it it was only a small quantity and I didn't need that last injection.
3rd and current pregnancy: bleed at 9 weeks no anti-D.
I had surgery (cervical stitch) at 20 weeks was given anti-D on the day of surgery and another dose the next day because I was bleeding still.
I then had the routine Anti-D that you are suppose to get at 28 weeks (I was later at 30 weeks because it was forgotten so remind them if you need too) that one was in the arm.
I was told this was a much larger dose and can still be found in your blood stream even post birth. But they give you another dose post partum just in case.
Having written my reply I've just realised I will probably end up with another dose on Monday at 36 weeks when my stitch is taken out.
One Postive, it toughened up my ass to injections!
I wouldn't worry to much they are very careful about knowing your RH status everytime you bleed or admitted to hospital.
