My period has been much heavier than usual this week, and the morning after intercourse one of my labias was swollen to double its size and it looks like theres a 3/4 inch dark red spot (maybe a scab?) on it. I was wondering if maybe there was a cut and something from the condom could have irritated it? Or maybe it's an infection? The dark red spot is the color of the clots I've been experiencing from my period, and is the same consistency, and where some of it (the scab or whatever it is) has come off is slightly indented - like it's a burn or something.
