To start off I've never had sex. One night I got a little crazy and did things with a boy I've never done before. He tried to put his penis in me but I told him to stop because I didn't want to do that so we didn't. However we did everything but have sex and he had a condom on for the most part. That was on a Saturday night and the following Tuesday I woke up with my period. It might've been a tad bit lighter than normal but not much, it was still heavy. However I haven't had my period sense, and it's 3 weeks late. I have symptoms of pregnancy I feel like but I cant tell if it's just me over thinking about them. I seem to be tired a lot and pee a lot but I work for 5 hours a day outside in the heat with kids everyday. It also seems that my Brest are tender and itchy but I'm 17 and before any of this my breast had normally been tender and itched occasionally. What I'm wondering is if there is any chance I could be pregnant if I never had sex and got my period that following Tuesday even if I haven't gotten it since?
