My cycles are always on time and regular. My husband and I are TTC. I had cramping and bloating a week before my period was due. The cramping went away and my period never came. My stomach still feels different like I am pregnant. I have taken pregnancy tests and they came back negative. I had one that turned positive but it was after the window that the test says to check. I am tired and nauseous too. I have never missed a period before or been late. I don't know whether to trust the test, wait a week and take another or just schedule an appointment
