can you start on some Pelvic Floor Exercises? Strengthening the pelvic floor has been known to help right mild/moderate cases of uterine prolapse. It is especially a good idea during pregnancy if you are at risk, so I would certainly start now.

I am not sure on the c-s though. I would be asking a separate doctor for their opinion on VB with untreated prolapse and what the risk factors are. Someone without a vested interest already.
