Bicornuate Uterus in Pregnancy Risks, Causes and Complications


I am currently 7 weeks 5 days pregnant with my first child. I had my first appointment with my gynecologist yesterday, and he informed me that I have a bicornuate uterus and my baby is in the right horn. I have been having irregular cramping but no bleeding, and my gynecologist doesn’t really seem concerned, but told me to ‘take it easy’.

My next appointment is in 4 weeks. I have read up a lot of information on bicornuate uteruses and mostly they end up in miscarriage in the second trimester. I’m really worried that I’m going to miscarry and I want to know if there’s anything I can do to prevent it and what the odds are that I will carry my baby to term and he/she will be healthy.

    I also have a bicornuate uterus. I am seven weeks into my third pregnancy. My first pregnancy ended at twenty weeks when my son was born, and my second ended in miscarriage around eight weeks. I have a good friend who also has a bicornuate uterus, and though she had C-sections for each one, she has three healthy children, one in elementary school, one in preschool, and one who is nearly three years old.
