Hi, my fiance and i had a sexual act on 11/11/2016, without penetration just fingering and hand job with 99% that there was not any contact of my orgasm with her vagina, in a week later 17/11/2016, i just fingered her, my nails was long and some dirt with rest of painting aerosol on it, she didnt get orgasm, on the next day she had and dark brown/black discharge, and other day just a mini spotting, after i fingered her she felt with iritation, burning on her vigina, after those two days she is ok with excelent health, no cramps, no mareas, no nauseas, everything is ok!! The next expected period is 26/11/2016, she still virgin. Can you help me what is the cause of that discharge? Before time she was with some burning on vigina and used some medication. Help plz.
