I had sex on the 6th of aug. and i've been on Birth control for more than 2 months. He used a condom too, but 3 days later i started to have stomach pains and nausea above my belly button and in between my ribs. Ive had nausea, bloating, and feeling gasy, and breast tenderness on the pill before, but right now i'm just paranoid. Are these birth control side effects? i dont think signs of pregnancy show up this early? help me!

Also He ejaculated into the condom, but i dont think anything leaked out or broke. and i started my period a week before (7/28/10) I had sex, so i dont think i was ovulating then. I'm on the second week of my third pack, if that helpful information.
