Hi Cari,
Like you, I'm a partial hyster. sistah too

I have my ovaries, but not the uterus or cervix. Thus, don't receive monthly periods - but I do ovulate each month....or every so often now.
What I did for a few years was to journal the monthly symptoms - did it in a 8 x 11 paper, added all my symptoms.... anxiety, crying feelings, depression, insomniac, doom/gloom attitude, bad mornings filled w/anxiety in a.m....well, a few more or less of the peri. symptoms for me. Anyway - then I would have enough space to X each symptom, with the date. I noticed that there is a pattern each month...when the feelings started, and when it ended. Also, another sign for me was the sensitive tender breast - I know I was about a week away from when I normally would of had a period.
Another way is to have blood work to show the estrogen levels, testosteren levels, etc. Your family Dr. or GYN can order the blood work. The levels tell you where you are in peri. I know for me it took about 3 or 4 times for the blood work to show that I was actually peri...when I knew I was for years. About 10 months ago or so - my GYN ordered blood work to see "where" I was. The number for peri. for me was 39... to be considered post meno. it would show 50 or higher...So I know I'm close to post... And I knew also because alot of the symptoms of peri...were slowly disappering or are appearing every few weeks or months instead of everyday....Yeah!!
It is so difficult to track things in peri. if you don't have a monthly period...when you have a period - it justifies why you've been feeling a little funny or out of sorts... I know during peri. for me not getting a period - I felt nutzy at times, not understanding why I felt the way I do...truly felt like going over the edge

...and then I found Power Surge... all those feelings others Sistahs had...I had. Of course, the GYN said I was to young to start peri. when I was 36 or 37...Boy was he wrong. If your Dr. feels your to young to have peri....demand to have some blood work. I'm now 48 (soon to be 49), and I feel better then I have in years...so I know my peri. days are just about over...
Hope some of the things answers your questions. Best Wishes Cari.
