I have a friend that has been trying to get pregnant for a few years now, she has been put on the fertility medicine clomid three times with two pregnancies that didn t make it past 10 weeks before she miscarried. Each time the doctors could find no discernible reason for why she miscarried. She has had problems with bleeding between periods and passing clots now for approximately 8 years. After stopping the last round of fertility medicine she started having a few hours here or there bleeding and clotting. She went to the doctor yesterday and he advised her uterus was the size of being three months pregnant but there was no baby and that is why she was clotting, but he had no idea why this was happening. she does have a family history of endometriosis but has been tested several times for it coming up negative. Her mother also suffered from hyper- ovulation . She has been to see multiple specialists without anyone being able to tell her anything other than her test results all say she is perfectly healthy and should be able to conceive without a problem and carry to term, and are not sure why she has these others problems.
