Usually during my period I seem to develop a small red lesion on my clitoris and the skin that surrounds it gets one. Not really much pain. No odd smell. No itching. And since I use tampons, there s no discharge. They go away usually a few days after my personal ends. I wear a pad or panty liner do the first 2 to 3 days along with a tampon just in case. I haven t noticed any build up either. Could this be from the pad rubbing when I move around or maybe the string? I tend to pull the string forward bc I don t really like the idea of it being near my bottom.
