I have had two normal, healthy pregnancies. In each case, I became pregnant right away. My children are ages 5 and 7. Recently, I began experiencing painful intercourse and painful urination. I received an ultrasound in which the only thing that appeared was that my uterus was bicornate. The fact that I had a bicornate uterus had never showed up with either of my pregnancies. The doctor was surprised that I had had two normal pregnancies. More recently, I became pregnant and had a miscarriage at 8 weeks. During the ultrasound to confirm miscarriage, the doctor (a different one) also mentioned the bicornate uterus with surprise that I had normal previous pregnancies. Is it possible that the shape of my uterus has changed? Could something be causing the misshape? I'm just wondering if their could be some correlation with painful symptoms I have been experiencing and misshape of my uterus. My primary physician has dismissed it.

It is highly unlikely that pregnancy changed the shape of your uterus that much. This is birth defect for a lack of better phrasing. When your uterus was developing while your mum was pregnant with you, it over developed and you had a bicorne uterus. You can have and deliver children normally, it is just more likely that you or your child will experience distress during labour and have need of an emergency c-section. There was a woman in my baby class who had a bicorne and the only effect was the child never turned. That is why they had the c-section.

My roommate had a bicorne uterus, they seem to be uncommon but not REALLY rare, and the only thing she complained about was the river of blood on her period. More surface area in the uterus, more lining to slough at the end of the month. As well it was extremely painful for her on her periods.

Your mileage will vary.
