Hi, i was wondering if theres a possibility of me being pregnant? My boyfriend and I have had unprotected sex daily for the past couple of days. By about the fourth day, I threw up a little in my mouth and had the need to use the bathroom. Ive noticed I was really hungry, exhausted, sleepy, nauseous, even a sick to my stomach feeling. But I got my period... it was small at first, spotted, then a regular flow.. not sure if Im being paranoid or just stressed.. what do you think ?
