Does anybody have some light to shed on my situation. I lost my first pregnancy and I am currently almost 12 weeks pregnant. The doctor says I have a very small amount of an antigen In my blood, so my fiancé is having the blood test to find out if he carries it in bothchromosomes. The doctor says she isn't overly worried but being a first time mom and loosing a baby previously. I'm really nervous. Some please give me some success stories
