A weird bump?

Casi
So I have a small bump in the left crease between my vagina and my leg. It isn't too bad but it's been there for about 1 1/2 months. It's under the skin, no head or anything, doesn't hurt unless I press on it. My mom thought it might be similar to a boyle or something. It hasn't gotten any bigger but it also hasn't gotten any smaller...
Have any of you had anything like this before? What do you think it could be?
