Had my last baby 12 yrs ago. Tore quite badly at the birth but stitched up fine. For the last 5 years I have noticed when I poo that there is a bulge that comes through the back wall of my vagina , it goes back no problem with a squeeze of the pelvic floor. Is this a prolapse? It doesn’t hang out, I can just feel it. It doesn’t bother me but is this something I should address with am operation, or will pelvic exercises do it? Is it likely to get worse over time ?
