I had similar symptoms for years - the hot flashes, insomnia, mood swings, terrible periods and some
weight gain. I kept telling my doctor I felt like I was heading towards menopause. The blood test always came back normal. Even up to a few months before my last period, I was sure menopause was just around the corner. The blood test said everything was normal. Sure enough, a few months after my annual exam, I had my final period. Everything has mellowed out and I feel wonderful.
