PLZ HELP‼️‼️‼️‼️

the scab thing is still on in this picture, but i picked it off and now it's irritated and itches like crazy. i put triple antibiotics on it, but i'm really curious as to what it even is?? ive also been having a lot of musty smelling discharge, and it's been itchy down there in general, also intercourse hurts, and made me bleed the other day which is very unlike me. i want to get rid of whatever is going asap so my boyfriend and i can get back to it before i start my period. please give me any ideas.

(sorry about my dirty finger nails..)
