Hello. So I just skipped my November period. According to my period tracker it was suppose to come on November 29th but it never came. I've never had sexual intercorse, I've only had oral sex with my boyfriend. Although one time we were dry humping. I was wearing leggings and he was wearing his boxers. He was near the opening of my vagina because I could feel it. He didn't ejaculate or anything, is it possible to get pregnant that way? I'm quite scared. I'm 17 and I started my period in 3rd grade. Also over thanksgiving break I recently began exercising and also Monday I recently did the Insanity work out. Could that delay my period? I've had the usual PMS symptoms but no period.
