I have periods problem. Periods are irregular from last few months. Periods come after the gap of two months. After two months when periods started it takes complete one month. In complete month period starts and stop. Not fixed. Are these signs of menopause. I am 46 years old. I am also using Cooper T from last 5 years. The Cooper T is for 10 years. I want to know my problem is the natural process of menopause or because of Cooper T.
