“Something feels like it's coming down.”

The short version

Prolapse is one of the pelvic organs slipping down from where it normally sits, because the tissue holding it has stretched or weakened. It is extremely common and it is not your fault. Two things are worth knowing before any appointment: which type you have, because the four types behave differently, and that you have four options rather than two — surgery and putting up with it are the ends of the range, not the whole of it.
