So I'm 8 weeks pregnant. I had my first ultrasound this morning and baby looks great. Ok so my doctors office just called with all my blood test results. They said all my blood work looks good except my antibody screen came back positive. I've had to get the Rohgam shot with my boys, and I got it at the very beginning of this pregnancy, but I'm still producing antibodies! Has anyone had experience with this?? I'm so scared my body is going to kill my baby.
