I think I have it? AF is here, my 3rd one since giving birth. I've gone back to using tampons and they've become a bit uncomfortable which I assume was just because I'd had a baby. Earlier I changed the tampon and I felt like something was coming out of me. I had a quick feel (sorry TMI) and it feels like there's a lot of muscle right at the entrance of the vagina. I don't think it's come out yet but it's right there Any ideas? I'm sure I never had this pre pregnancy.
