Hi, Im 15 year old teenage girl. Im very small, so my period isnt usually regular. However, it has been regular for a few months now. My boyfriend and I have not had sex, nor have we rubbed genitals. We have done fingering, hj, and oral sex, but he has not cum since my last period. My period is late, and my boobs are very sore. I also had a small spotting thing, but it was very, very slight. I didnt even notice it. Its just small little marks.. like "tire tracks" for men i guess? People keep telling me that since i havent actually touched genitals or had sex, i cant be pregnant...are they right? Am i just having normal pre menstural symptoms, or should i be worried?
