Hi Karen!
I knew SO LITTLE about menopause and had never even HEARD the term perimenopause when all MY craziness started about ten years ago!
The symptoms were many and varied yet VERY TYPICAL from what I have now discovered as I talk to more and more women.
Somehow I just thought menopause was a sudden stop of menstrual periods and that was IT! I didn't realize all the stuff that came along for the ride!
Walking WILL help. Losing weight will, too. From what I can tell in FINALLY talking to a lot of people who are also going through menopause, every woman's experience is a bit different from other women, but many symptoms are common.
My menopause was complicated by a fibroid that grew back ten years after I had it removed. I had ten years of regular periods for the first time in my life which was really weird to me! Then about ten years in (about ten years ago), the symptoms which I now know were perimenopause started in earnest.
I had heavy bleeding for FOUR YEARS. I became anemic, and also gained weight. It wasn't pretty!

I didn't want to have the fibroid removed AGAIN because this time I knew they would want to remove my uterus right along with it. I've had two C-sections and a myomectomy in eight years, so I do NOT want anymore abdominal surgery unless it is some emergency. I opted to wait it out about the fibroid thing, knowing that I was almost into complete menopause. The heavy bleeding to me was a lot like the finale at a fireworks demonstration. I KNEW that it couldn't go on forever. I waited it out.
I am period-free now which is SOOOOOOO wonderful after keeping the tampon and pad manufacturers in business for so long that they probably could retire and move to the Bahamas on the $$$$ earned just from all the products that I bought from them over those four years! When I went on vacation to Florida HALF of my carry-on was pads and tampons!
I'm glad that I played the waiting game because I DID NOT want any more surgery. At the time I was a lot heavier than I am right now, and I also did not want the extra complications that weighing a lot can bring to a surgical procedure, either!
Hang in there. Do a lot of research and get second opinions. Talk to as many women as you can to get their take on things. It will work out for you!
