I have a subseptate uterus, which is a heart shape uterus, with the septum that divides it in half.

My first pregnancy I PPROM''d at 33 weeks and delivered DD1 just over 2 hours after rupture, VB no drugs (birth story in my sig), but I had polyhydromnios (too much amniotic fluid, which was probably the cause of the rupture but it allowed DD to spin, she was a posterior birth but all good

We encountered lots of issues with DD2, I had low amniotic fluid (who would have thought I could have the complete opposite!) and a raft of complications, DD2 was breech at all bar one appointment, and I tried everything to get her to spin and stay head down but it didn't work. My OB attempted an ECV at 28 weeks (extremely rare to do it so early) and I doubt that many OB's would make the attempt, but it was our only oportunity as it was when my waters were at their peak and we weren't sure if I was even going to make it to 30 weeks so she gave it a shot. She made two attempts, DD2 turned and then went straight back, she wasn't at all interested in turning and staying turned. I was already being medicated for contractions and from that point ended up on bed rest until delivery.

She was supportive of breech delivery if my waters broke or we had to progress the delivery, but it didn't end up happeneing, in the end I had a CS (birth story also in my sig )

But you can have a VB, perhaps look into Breech delivery and see that is an option for you, and I would just look on Spinning Babies as there are a few (not all) things that you can do now to try and get the baby to turn

All the best
