hi , im 25/f single. i have been experiencing irregular bleeding since quite long.My cycles used to be irregular but i used to get my periods every month somehow but may b not on the same time everymonth. I was diagnosed as polycystic ovaries.For past 1 and half month i had continous bleeding so i was advised to take duphaston 10 mg twice daily for 5 days and i did.my bleeding stopped.i was told that i would get withdrawl bleeding but its been more than 4 days that i havn't got my periods.Is there a problem?What should I do to bleed? I have been taking metformin as a maintenance for pcos.Is there anyother drug that you could suggest other than the contraceptives because I'm already overweight.Hope you could help.
