Hi am 48 years. In February my periods did not come, then in March my periods came for a few hours. This month on 5th my menstrual was so heavy like someone who has had a miscarrage. After that i have been bleeding on and off for 2 weeks now. Yesterday i went to the doctor and he prescribed the following medicines. Sylate 500mg and Steron 5mg. After taking this, i have notice reduction in bleeding. What could be the cause of this?
