So my fiancÚ and I have been having sex almost every day since I got off my last period because we are trying to get pregnant. My next period is due tomorrow (3/6/13) but normally by now I am spotting and having horrible cramps. However minus a few cramps now and then there is nothing. For the last 2 or three weeks I've had slight cramps. Upset stomach. Clear/white discharge. Head aches. Fatigue. I feel bloated. I have to pee more than normal but not constantly. I've taken 3 HPTs and they all came back negative. Is it possible that I am pregnant? What should I do?
