I am 52 and have not had a period for 12 months. but I started having bad hot flashes and sweating all day and night. I went to a the doctor he gave me a sample of femhrt low dose. it stopped the hot flashes but I got a period now for three days today. is that normal. I don't smoke and always had my period on time. I wanted to know how long the bleeding stays. is it llike a period .
