Hey other bicornuate uterus women! I just wanted to make this post because I couldn’t find any on here when searching. To begin, they discovered I had this during my cesarean with my daughter and now I’m pregnant with #2. So I started bleeding heavily and then passing clots. I immediately thought I was miscarrying so I went to the ER. Turns out it can be normal for the horn to shed its lining and my baby was fine. Didn’t have this with my first pregnancy which is weird. But if you start bleeding dont assume the worst because it could be the other horn!
