My boyfriend and I have dry humped multiple times, he has taken his clothes off, but I always leave mine on, one of the times though I was wearing only underwear and some thin PJ pants, he was naked, and I dont think that my cherry has popped, unless it is possible to happen by a tampon and I didn't know about it? Any way I have been getting a lot curvier, and I have been spotting, and I have been more emotional, I am 18 days late for my period, do you think I might be pregnant? I am so scared, my boyfriend says that it isn't possible, he has pre-cummed on me before, and I dont know if that is possible for me to pregnant, I am freaking out!!!!... I am only 16 and this is my worst nightmare....
