Thanks for posting your query.
is an inborn error.
There are increased chances of miscarriage
with septate uterus as compared to normal one.
But don,t worry,have proper rest & consult your doctor regularly.
There are many factors to decide whether you can have normal labour or cesarean section except septate uterus. So it would be better to think about this matter at term gestation.
If you have any further query please let me know I would try to answer it for you.
Wish you a great health
