Yup, I was about 38 when I started having vague symptoms. By 42 I was going 2-4 months without a period, and they got really heavy. I had all the terrible pms symptoms you could imagine and they got worse. I went for eleven months without having a period, two times, at age 45 and 47, and finally, when I was 48 they stopped for good. Ten years. I only had hot flashes for about 2 years after it totally stopped.
