My boyfriend and I have been very intimate lately but no sexual intercourse; he ejaculates on the bed. I was supposed to have my period on October 4 but instead of that, I ve been having this brown discharge which happens once or twice a day, and a very light red color when I wipe probably once a day, no period. His ejaculate might have touched me or some might have been on his finger when he insert it into my vagina .Please help, I don t know if I might be pregnant or is there any explanation for this ?
