How quick does a prolapse happen?

In March 2026, I had a transabdominal and transvaginal pelvic ultrasound done for pain I was having. Everything physically seemed fine back then. No issues were found from the ultrasound. Fast forward to mid May, and I get my period and can't put a disc in and realize my vaginal canal feels different. I suspect I have a prolapse. Between March and May, would a prolapse happen that quick?
