I had my cycle from 9th to 12th dec, my cycle avg is 24-26 days, had intercourse on 16th dec with protection, took ipill on 17th, started bleeding a week after that for 3-5 days, then again on 3rd jan which is my regular cycle date, until 6th light bleeding then heavy until 14th january. Due date of cycle is 29th january, but has been delayed. Could you please advise and elaborate on this issue? Thank you.
