The other day I found a small, pea sized bump inside my vagina. It's deeper than my inner labia, actually more like the wall of my vagina. I'm going to the doctor today for a routine pregnancy checkup (I'm just starting my 3rd trimester), and obviously I'll be asking about it then, but I was wondering in the mean time if anyone had an idea of what this could be. It was too far in (and too hard for me to balance my big, round self) for me to see with a small, handheld mirror, so I'm not sure what it looks like. Oh, and my husband and I have never had sex with anyone aside from each other.
