hi to miss one or two periods is not such a bad thing mind you it does worry the bejesus out of you lots of things can be behind it. one would be just nothing your body can do that without thinking. perhaps your stressed? gone on a low cal diet? been doing extra exercising? been taken any out of the way meds lots can do it. hope this helps if not just go see your doctor a blood test would tell a lot. good luck
i missed two periods and took hpt and came out negative and havent got any pregnancy symptons what can be wrong?
