Helloo I hope all of your pregnancies are going smoothly and you and your little bean(s) are healthy ! I found out at my 13 week scan that my blood type is rhesus negative and it was explained to me that, although this pregnancy will be fine, any pregnancies after this one will be in danger of miscarriage if the baby's blood type is positive because my blood will reject it. Anyway, I know that I have to have an injection at 28 weeks to stop what I just mentioned happening, but is that it ? Is it one injection at 28 weeks then I'm fine, or do I need more injections further on in my pregnancy too, or maybe even after this baby is born ? Thanks ladies.
