Hi, sorry for your loss.
I have a bicornuate uterus, I’ve had two miscarriages which may or may not be to do with the womb shape, I suppose miscarriages rates are high anyway.
I have two children, with my first I knew I had a bicornuate uterus but was spectacularly let down by the hospital and wasn’t put as high risk, ignored when I was in labour and he was born at 24+6.
However with my second I was offered progesterone pessaries, and growth scans at 16,18,22,24,26,28,32,36 weeks. Baby got IUGR and was delivered at 31 weeks. Both children are beautiful and thriving now.
I’m not saying those things to scare you.
When I trailed the internet I found the opposite to you, I found thousands of comments of people that said their baby was fine and full term and it wasn’t a concern at all. From what I gather how severe the septum is makes a big difference. My point is it can go either way, you could have a full term bouncing baby, you might have a bumpier road. My advice would be to make sure you’ve got a good consultant that knows your worries, get a good care plan in place where you know you’re being monitored closely with lots of scans. And then try not to worry as much as possible. It’s easier said than done but you’ve got a good chance of everything going well and you don’t want to ruin your pregnancy before it’s even started.
Best of luck OP.
