I am 16yrsold. and I am feeling dizzy and my tummy hurts like i just finished doing my push ups and im so worried to death, if i am pregnant. Is that a sign for pregnancy? :(( . Last week ago(January 14), I can't say i had full sex with my boyfriend. I held my boyfriend's thing and put it in me. the whole thing didn't go in me, there was no full penetration, only 1/3 of it and because im still virgin(my first time, and it was too tight). So we decided to stop it.. though it hurt me a lot physically and ALSO my boyfriend didn't want it, he was scared. He didn't ejaculate but he was worrying if he pre-ejaculate.We did it only for only 1minute or less. My last menstruation start date was January 5.Please help me.
