Please respond, I have regular cycle and never took any pills before. I took ECP 1st time on the same day of intercourse, which was the day before my normal period should have happened, I got my period 2days after intercourse with cramps same way i got last month. But the problem is i had 5-6 days cycle and the bleeding would cut out but now it's 5th day and i am bleeding just like the 1st day. I am worried, has ECP contributed in my bleeding? Does Ecp have any harm to my period that will come tomorrow if i take ecp today. I am concerned about my bleeding it's same even on 5th day of period. What to do? please help.
