okay... so a few weeks ago (3 weeks) i had sex with this guy. we first started without a condom but then i got scared and a few minutes later insisted that he put on a condom. he didn't cum i know that for sure. but i don't know if i'm pregnant or not. is it possible? Im only 16, and my periods have always been irregular. like I got it for the frist time in november, had it for 3 months and then got it again about 3 months later. Im really thin and really active. lately though my breasts have felt tender and sore. today i went pee and when i wiped there was a bit of blood so i thought i was getting my period. but when i went to the washroom later there was nothing. Sorry if thats alot of information. all i remember is that the few days after sex i was having a funny coloured discharge. im really worried about this. please help me!
