My husband and I have been trying to concieve for almost a year. My OBGYN prescribed Clomid for use during previous cycle. I am now 4 to 5 days late and have always been regular. I had no PMS symptoms before my cycle was due and have also, always, had them. Now I am experiencing tender/larger breasts, a greater amount of vaginal discharge, slight cramping in my lower left abdomin, and bloating. I took a hpt and it was negative. Do I have reason to believe I am pregnant and had a false negative hpt?
