My last period was around September 25, 2016. On around October 15, a guy took advantage of me and ended up rubbing his genitalia on my lower butt. no penetration, just rubbing around that area. to my knowledge, he didn't ejaculate. however, after he did that, he fingered me. about a week or two later when i wiped i noticed a little bit of blood on the toilet tissue, but it only happened once so i didn't think much of it. I am just really worried that somehow that small about of contact got me pregnant because that was around the time when i would have been ovulating.

My periods have never really been all that regular, but they usually show up after a month or two. so i'm just stressing myself out that i could possibly be pregnant. i know it's irrational to do, but i can't help it!

fast forward to December 23rd and still no period. however, i haven't really had any symptoms of pregnancy. my breasts have been normal. no usual amount of fatigue. no food cravings or adversions. no emotional episodes. it's all been business as usual. however, last night i noticed that my belly looked a little fuller. i'm a bigger girl with a little bit of a tummy, but the bottom part of my abdomen looked bigger and seemed to feel a little harder than usual. so naturally, i poked it. my finger still bounced back when i poked, but it just felt a little hard.

the only reason (other than an unlikely pregnancy) that i can think of for missing my period is that i have just been so stressed that it's chased it away, because i've heard that stress can play a big factor in a female's menstruation.

this may all just be in my head, but i'm really freaking out. i'm only 16 and i don't know what i'd do if i were pregnant. i am probably just stressing myself out for no reason, but i really just need some help!
