Hi, I am O- and I just had a miscarriage last week, the doctor said that because I am O Rhesus - I needed and anti D injection just in case my baby's blood had escaped into my blood stream. The only way you can have trouble with this is if, A. You have had a miscarriage B. you have delivered a baby before. I have had an anti D injection with every baby I have had, I think it is standard practice. I don't know if your first miscarriage was your first pregnancy or not.
Yes, my first Mc (3months) was my first pregnacy. I then got pregnant 5 months after that and it also ended in mc( 2 months). I will have to ask my dr about that shot.
If you are o+ you can carry a rh negative baby with no issue. If you were o-, you would need to pursue the injection. I would look into other miscarriage-related issues. Antibodies to the baby tend to get the most play time when looking at information from reproductive immunologists, but it is controversial. I'm sorry for your losses!
