Ok, here's the deal. Last month my period was 2 days early and only lasted 3-4 days with this weird brown discharge/spotting stuff at the end. that was last week. Well today I am having cramps in my lower back, my stomach is a little upset and I really don't have much of an appetite. Along with that, smells are making me completely nauseous! My b/f and I had sex all month long no protection, b/c we are ttc. Could I be pregnant???
