Before he met me, he was in a relationship with a girl and they found out they were pregnant. Shortly after they found out she lost the baby.

Anyway, I have found out I was pregnant twice within the last 9 months. We have never been able to go to a doctor to have proof of pregnancy because I wasn’t pregnant by the time the appointment was scheduled. Two chemical pregnancies and nothing seems to stick. So we have given up and are no longer trying. (But we aren’t preventing either)

So here my question: what could be wrong? His sperm? My uterus? My eggs?
