I have been ttc with my new partner for nearly two years now. In that time ive had 3 chemical pregnancy's. My sister has told me because I have o neg blood my body could be seeing our baby as a foreign object.( Im not sure what my partners blood group is) I had my son (previous relationship) 11 years ago I was given anti d after each pregnancy my question is do you think that its because of my blood group that I can't carry my fiance baby ? Could I ask for anti d before I get pregnant again ? Or will that anti d still be in me after all these years ? So confused all I want is for us to have a healthy baby and il be devastated if we couldn't because of me.
