Thanks for using Justanswer for your question.
Sometimes people get folliculitis which is actually ingrown hair. You would have some other sympXXXXX XXXXXke pain or redness, or itching.
Perhaps your weight has settled and it is just a fat pad.
If you start to have any symptoms such as a fever, redness, drainage, pain, then I would suggest you see your gynecologist for testing.
If you have other information about this or questions, don't hesitate to right me back on a reply.
