Hi, I had my last periods on 22nd October. Usually next period comes for me after 28 days. Following this, i m expecting my next periods on 18th Nov. But I m getting married at that time and want to prepone my periods. My doctor has suggested me to take REGESTRONE (Norethindrone Acetate 5 mg) from 3rd Nov to 10th Nov for 8 days, once daily. He said I will have periods 3-5 days after i stop my medicine. But i have read in internet that this medicine is used to postpone menstruation . Is my doctor s suggestion correct?
