So recently I notice this bump on my vagina. Its not small but its not big either. Its soft but it kind of hurts little when I touch it. Also I get this tingly feeling around that area. There's no liquid stuff on it or its not dry either. I had the same problem before but it disappeared. Now its back again but its in a different place. The first time I had it on the upper part of my vagina like by the groin and now its by the labia majora. And I notice that when ever this bump appears my period skips. Idk maybe its just me. I'm worried about it. Is it an STD?
