I am 37 and think I've been having symptoms for the past 1-2 years. I've had hot flashes, night sweats (only 2 or 3 times), heart palps, etc. My period has been a little screwy since November last year. I have never missed but had ones like yours...3-4 days and 7-8 days, some months a lot and others not so much. I never know how long they'll last. The age thing...hmmph! I've been to my gyno and he said that some of the symptoms I describe he would see in a woman 10 years older. I went to my GP last month for a bladder problem and he made the comment that "I was too young for menopause". I piped right up and said "Not necessarily" and went on to describe some things I've experienced. My doc has a sense of humor but I think I left him speechless.
When did your Mom go through hers. They say it usually follows. My Mom had a hyst at 44 and I thought I couldn't gauge my experiences with hers, but when I asked her about any symptoms prior to the surgery, the info she gave me had her having hot flashes in her late 30's.
I would see your doctor, but from what I've read on this board, the messed -up cycle is one of the first indications of peri.
We "youngsters" can definitely go through this at our age. I truly believe it. Now....to find a doc who agrees.
