Does this sound normal? I have googled "causes of early menstrual cycle" and really didn't get anything about it. My cycles have been overall normal for the past couple of years, and my cycle is prone to changing every few months, but not by more than one or two days. For example, it came on the 20th of the months for about four months, and then it came on the 18th. Then it went from a 30-day cycle to a 28-day cycle. But I have never had a cycle as short as this most recent one (only about 22 days).

For the record, I have not been under any tremendous stress (a little minor stress here and there, like most people have), have not begun any exercising, no significant weight gain or loss, and the only change in my diet is that I have been eating a little less than usual in an attempt to lose those pesky "freshman 15". Also, I am not on birth control, or any medication for that matter. Anything that would cause a change in my cycle has not happened or was not used.

I also want to add this...All the symptoms I normally get prior to the start of my period, I got. I noted the classic change in discharge as well as light soreness in the sides of my pelvis where my ovaries are. The blood isn't a different color than normal and is not any lighter or heavier than normal.

Have any of you ladies ever experienced this? Does anyone have a suggestion of what it could be?

I wasn't worrying before, but now I kind of am. I don't know if my cycles have just decided to be out of whack for no reason, or if there really is a problem. I would sincerely appreciate any advice on this at all.
