So I'm a 21 year old female. I have been masturbating since 12 but never had intercourse. This year I noticed that I start having this mucus discharge with red blood in it Every time after I masturbated. No foul smell, only blood smell. It usually comes when I wipe after peeing. There's still over a week before my period will start. I did not insert anything in, only use my fingers to rub until I orgasmed. Should I be worried?
