My wife is 50 years old. She did not get her menstrual last month and this month it resumed but even after the completion date the flow is still on and our family doctor has prescribed a tablet etosys 6 to take for 3 days twice a day. Today is the 3rd day and she has consumed 4 tablets as told by the doctor. This morning the flow is as same as the previous days, no changes. Please advise.
