pregnant?

Okay so, on Feb 7th I had sex. I had finished my period, and it was 3 days after I had started a new month of birth control pills (I've been taking them for a few months now.) He wasn't wearing a condom but he pulled out. This week I've had multiple symptoms come about. I've had massive bloating, and tender breasts, A LOT of cramping and slight nausea. On Tuesday I had even got dizzy and fainted (I've never fainted before in my whole life.) I've been good about my pills but im terrified.
