Okay last monday i was dry humping for a long period of time. He had on basketball shorts and briefs i had on leggings and underwear im pretty sure he did not ejaculate because i didn't have any wet spot on me. When i went to the bathroom i had brown-ish reddish discharge that only lasted about a hour if not that long ( im still a virgin by the way ). What could it have been that caused it? My last period was on the 21st of May n now i thnk im have PMS at the moment. Should i be worried about pregnancy? Thanks
