Am I Pregnant I’m fifteen years old.

Patient: For the past 2 wks my stomach has been feeling really bloated. It usually gets bloated before I start my period. Me and my boyfriend had unprotected sex. Now this is my 2nd or 3rd day feeling weird. I threw up both mornings the first time was clear but when I spit I saw blood. I also have diarriah. I don’t have dizziness and my breast don’t hurt or feel tender. I took 2 pregnancy tests today and no results have showed. Could this be the sign that I might be pregnant. I’m only 15.
