Marydean, I'll ask my Mum more about this one ...

She had four children (thus four pregnancies and births) and had a very severe uterine prolapse by the time her 4th was about 5yo (i.e. part of her uterus was hanging out of her vagina, external to her body).

Anyway, I didn't mean to freak you out, but wanted to say that I presume that she had a milder version of the prolapse for quite a while prior to this time, and managed to have 4 very healthy pregnancies despite what was probably going on with her uterus.

I'll email her and ask her when her prolapse first started.
I hope you get some good answers after talking to your Dr.
