Found out today that I'm a carrier for a spinal muscular disease, but there's no sign of it in my family. And my husband is a carrier for Joubert syndrome 2, but there's no sign of it in his family either. Could this be the reason for my multiple chemical pregnancies? My husband is a little worried about continuing ttc now from fear of passing these disorders to the baby. I don't know when I will be able to talk to my doctor about it, so does anyone know about this stuff? I still want to try.
