Help, iI haven't had a period since April 09 and its now July so I am 3 mths+ late negative pregnancy tests, blood tests normal for hormone levels, and scan clear and no visible pegnancy. What could be wrong with me?? :confused:

Any recent changes in weight, diet, and or exercise?

+1 to what justcurious55 asked, also, how old are you, when did you start your period for the very first time, and have you ever skipped a month or 2 before? I skip months ALL the time. It sounds weird, but sometimes an irregular cycle can be 'normal' for some women.
