So as i remember my last period was november 30, 2012. My period is usually on time, im only 3 days late but i get paranoid really fast. i wasnt excatly sexualy active but there was some rubbing involved, he was wet, I've checked online for the day i was suppose to be ovulating and during that time i did not do anything. Usually when im about to get my period my breast start to hurt but not this time but i have noticed a couple pimples which is a sign that im going to get my period soon. but one thing that did happen last night was that i threw up??? i know there is a possibility i can be pregnant but with me stressing out i dont think its helping out at all. I'm really hoping im not pregnant im scared and im a senior in hs and im moving on to college, and i cant afford a baby right now?? PLEASE ANYONE ANY ADVICE??
