Ok so i got off my period July 10 last Thursday and last Saturday night me and my bf has sex unprotected but he pulled out then later that night we had sex with a spermicidal condom. We had unprotected sex in the past also about a week before i got on my period. The next morning, i started feeling sick and throwing up. It has lasted until today and i still feel dizzy and have a head ache but not nauseous like i was before, but i do also have a small stomach ache.
For the past few days everything i ate would make me sick, and i have lost about 8 pounds

Does this sound like just a normal virus or could early pregnancy symptoms? I really dont think im pregnant but im just worried that i could be, since we were having unprotected sex. I have had all my periods though
