I'm 17 & I've had sex with my boyfriend for the first time on April 17th. I had just got off or towards the very end of my period the day before. we used a condom then discovered it broke but he didn't ejaculate inside of me in any form. Now it's the 13th of May and my period still hasn't came. I usually get it between the 8th-10th. I'm not feeling anything except a little upset stomach and slight headache but I've been feeling that way before we had sex. what is going on??
& I've been really stressed between prom and exams, school work etc
