I've never had sex but my boyfriend and I have messed around several times. I'm not on birth control so could I be pregnant? On June 24 I took a plan b pill and I started bleeding lightest for a week afterwards. However recently I've had to pee more often, my boobs are tinder, I feel like my areolas are darker but I'm not sure. I have been nauseous or been craving anything or been afcted by certain smells though. Do you think I'm pregnant?
