I have a 30-35 day cycle ...me and my boyfriend were dry humping around the 14th day...there was absolutely no penetration he had his boxers on and i had my underwear and a skirt made up of very thin material...we dry humped for quite a lot of time and toward the end i noticed some wetness on his boxers which might have even touched my bare thigh and skirt sometimes ...im really concerned what are the chances of getting pregnant by this? Should i take an ipill it isnt 72hrs yet
