I think I might be pregnant? I am very bloated to the point now that I have to undo pants to relieve the pressure, I am getting dizzy, and headaches my breast aren't sore but they feel very heavy, my nipples are tingley I also cramping alot. My cycle is due next week and I ussually get pms 2 weeks prior but not like this. Can someone help me give me some advice. Last months cycle was light and only 3 days.
