My periods have been messed up for about 3 months now like I'm on a week then off a week then I was taking some antiobotics and started itching around my Virginia so I went and got some medicine for a yeast infection and before I used it I noticed a bump was on me down there so I waited until today to start using it and now 2 more bumps have appearedthey are very painful and at first I thought maybe they were infected hairs but I don't really know they are under the skin you can't really see them but you can feel them

It isn't wise to guess something is a yeast infection when you don't have yeast infection symptoms.

Have you asked your Doctor? It might be hormonal.
