I was suppose to start my period yesterday morning. I didn't and I haven't really feel like I was going to. Though, I have had a sore stomach(like I have worked out for a couples days in a row, Muscle soreness) and a few cramps, it is sore if I push on my lower stomach. I took a pregnancy test last night and it came up negative. The line was kinda faint though(I think). I live with another girl and she is having the same problem. We usually start around the same time and neither of us have started. Please help me. I need some advice.
