Prolapse

I just had my first baby in June. About 3 weeks postpartum I noticed a bulge on the inside of my vaginal opening. Went to doctor and he said it was a prolapse. A rectal prolapse aka Rectocele, where the wall gets weak and my rectum is pretty much pushing that walk into my vagina!!!!! Ugh!! Wtf! Didn't even know it was possible! Awful! He told me to do kegals. Just wondering if anyone else has this or has had a prolapse before?
