Hi Jessica,
I just wanted to say congratulations on your pregnancy.
I have no experience with a subseptate uterus, but i have had 2 miscarriages and then a wonderful baby boy at new year. Unfortunately, miscarriages are common and may be more common than you think because people don't always talk about it. You are certainly not alone.

It is always difficult, but try to relax and enjoy your preganancy. You need to look after yourself and it sounds as though your doctors are taking care of you, which is good. With DS I had a really positive feeling that the pregnancy was a good 'un and all was going to be well, I hope that you can have that too for this pregnancy.

Good luck, sending sticky vibes.
