So im 17 I had sex a month ago did (not use a condom) while on my period but I was just getting getting over it I only had sex with the guy for like not even 2 minutes and made him stop he said he did not cum and I know he did not cuz well I gave him a hand job after Cuz he did not cum. But its been a month now and I have missed my period by 3 days now and im getting worried I could be pregnant by the precum, but my friends say my period has not came yet cuz im stessed put about the finals that are going on this week and im stressing out over me might being pregnant, I have no symptoms of being pregnant, I randomly gett wet a day before I get my period but its been 3 days of randomly getting wet and no period...could it be from stress?
