Hello Doctor, I took Deviry 10 mg twice a day to delay my periods from April 20th, 2017 to May 2nd, 2017. On May 7th I got my periods. But it was not normal & after 2 days i had heavy bleeding which lasted for the next 7 days. In June, My periods started on June 8th, again the bleeding was very little & from june 12th I had heavy bleeding till June 17th. My usual cycle is of 26 days. In july, it started on 2nd & with heavy bleeding on the first day itself. Is this pattern due to Deviry medication?
