I have had sore boobs for almost 2 weeks now and i have had slight nauseous without throwing up. Pms feeling cramps and more thirsty than normal. I am technically supposed to start in about 4 more days but i have pcos and my periods are extremely irregular. I had sex on the 2nd, 7th, and 16th of this month with condoms and im on the pill but i miss pills often. I have take 5 pregnancy test over the past 2 weeks, at all different times of the day, but they are all negative. Do you think in pregnant or just freaking myself out?
