That bulging feeling is similar to what I had, it wasn't apparent the first time I asked a DR about it, but later on after asking for a second and third opinion it turned out it was a prolapse.

However, after time it did sort itself out. I'm talking several months. Keep going with the pelvic floor exercises, if necc book yourself into an incontinence clinic to make sure your technique is good (turns out what I thought was a pelvic floor lift was only half a pelvic floor lift).

Even so, I was horrified 9 years later, after taking codeine (which I never normally do) and getting constipated as a result, the prolapse recurred. Only as long as I was constipated. Then it went back to normal after a couple of weeks again.

HTH. Try not to worry, it takes time. BTW my sex life is better now than it ever was pre-baby (cos I think that's what you're really worried about) so it's not all bad news.
