I'm an A- and I got it for my first two pregnancies. It was just an average needle and they injected it into my bum from memory! It didn't really hurt and was no big deal.

And yep, you usually get two injections during pregnancy and one afterwards if your bub is a positive blood type. Both my boys are A- too and we worked out so is DH so I don't need the injections this time. Spewing I had to have them the other times, but we weren't sure of DH's blood type back then.
