Right, I've noticed during my last few periods that sometimes (but not every time) it feels like I can't get the tampon in properly. It either feels a bit 'stuck' or uncomfortable like it's not in right. Sometimes after a couple of hours it feels like it's falling out too.
So I've wondered prolapse and had a look but to be brutally honest I can't tell if it looks normal or not! But:
Sex is ok and not uncomfortable
I don't leak urine ever, not during exercise either
I can hold my wee mid-flow
Would this rule out a prolapse? Have I just got a weakened pelvic floor? Don't know what pelvic floors I'm meant to do 
Btw have had 3 DC one of whom was 10lb+ at birth. All vaginal deliveries.
Thanks!
