A couple days ago I noticed swelling in between the bottom of my vagina and my anus. All around the bottom of my vagin on the outside of my labia major it's all red and swollen. In between my legs and labia major it's red and hurts when I touch it. It's like a small rash. but when I touch it its hard. Like I'm feeling a gland. I also found a white bump on the bottom of my labia majora. It's small. The whole area down there is red and puffy. Me and my boyfriend haven't had sex in over 2 weeks and I recently started birth control. Can some please tell me what's going on?
