While showering I found 3 black raised bumps on the lips of my vagina. I have not been sexually active in quite a few years so I know it has nothing to do with that. They seem to have popped up overnight. I didn't feel them when I took a shower yesterday. I haven't shaved down there in years but I use to and have had ingrown hairs and know what they look like and it's not one of those. It's also not a bartholin's cyst or a sebacious cyst. Already looked those up and they don't fit what I'm experiencing. They don't hurt and had no clue they were there until I washed today and then looked at them with a mirror. Any ideas?
