My menstrual cycle is disturbed due to hormonal issue. Doctor advised me to take the dose od diane35 pills for 21 days. I've taken it's dose regularly for 21 days but still there is no sign of periods. I feel the pain which is like before periods but periods are not coming. From last 3 months periods have not come. I am 19 years old and unmarried. And 6 days have passed to give the break for periods after taking yhe dose but still periods have not come.
