Well usually they give you a shot in pregnancy so that if your blood and baby's blood mix then you don't have a problem. You only need the shot once so hopefully you have had it they should give it to you even if you are miscarrying. So that shouldn't be an issue
Actually, you have to have the shot 2 times.. Once while your pregnant, and again right after the baby is born so that if you happen to have anymore children it builds a resistance in your body to help protect you and your next baby....
I am O- and I have 4 children and never had any misscarriges. You will need a shot during pregnancy and after baby IF your baby has a positive blood type. You will never build up any kind of resistance over time just because you have had the shot onece or twice. If I ever have a 5th baby I will need the shot again regardless. If you have a late misscarrage you will need the Rogham shot also. Okay I am not %100 positive on the shot after misscarrge, but I think so.. Having a baby today has never been safer even with having an RH negitive blood type:~)
What is BC uterus?? I also have a tipped uterus but have never had any issues.
When I had a miscarriage they tested my blood to see if I would need the shot but i have positive Rh factor so i didn't need it.
