I had unprotected sex 2 weeks before my period started, I got my period normal like always. A few days after my period ended I started getting really fatigued, strong smells make me nauseas, heavy discharge (which usually doesn't happen), my breast have been sore for the last 2 weeks, and I've been having lots of cramps. My next period isn't due till a week. Idk if it's too early to do a pregnancy test.
