Hi, Can ipill mess up period cycle and delayed periods unto 12 days. I had ipill on my last day of periods (periods start on 15 jan) on 19 jan. After 7 days I had heavy withdrawal bedding on first day then less on next 2 days then stop. Now my periods due date was 15-16 feb. But today is 27 feb almost 12 days delay. So I want to ask: 1) How long should I expect my periods and wait 2) after 3 day withdrawal bleeding is there any chance of pregnancy? I am very worried please help. I already ask this question many time but didn't get any complete satisfactory answer.
