I;m usually never late on my period and I'm 16 and I've had it since i was 12. I've had sore breasts and completely broke out all over my face and have been getting some cramps, but not as bad as i usually get my first two days of my period. My boyfriend and i do mess around a little bit and we tried sex but he had on a condom and never fully went in me. He's also never came while messing around and stuff. I don't know whats wrong though.. is there still a chance I could be pregnant? or is it stress?
