Girls, hi everyone!??? When you register at the antenatal clinic, do you have to get your blood tested for Rh incompatibility with the baby? And at what week did you get it done if you have a negative Rh? I'm thinking maybe to pay to have it done at Olimp or Invitro, since it's already possible from 8 weeks.
