I was told when I was 38 weeks pregnant with my second I had antibodies in my blood. That's it, that's all. No explanation. Now I'm 15 weeks pregnant again with my 3rd and the dr told me I have antibodies, but got a LITTLE bit more information this time around. I have the antibody anti-E and I need to be monitered. I Got a card this time too. Any one else have this and can share their stories and give me a little more info. I did a lot of googling and scared myself..
