Hi, New Crone -
Mary is right....

I could say "me, too on much of your history - and for sure the cycles and their dates. Mine is at an average of every 23 days for the last year, but they can be as short as 14 days, as long as 46. Oh, I just turned 44, by the way.
I have had those cramps at all parts of the cycle, I know just what ya mean.
I made myself nuts with worry - and being married, and knowing I would keep going thru the worry, I finally bought pregancy tests in bulk at one point.
I never did end up pregnant.
The chances are very, very good that your hormones are leading to this stuff - but, since worry can actually mess with you in other ways, If I were you I would take a test...anything over 28 days from your last period, and it should provide accurate results.
Hormones can be a blast, hunh! ?
I feel for 'ya!
