So my cycle was from 9th to 12th dec, had intercourse on 16th dec and took ipill on 17th dec. Started bleeding on 23rd for about 3-5 days and then again on 3rd jan since this is my regular cycle date, it was light until 6th jan and started a bit heavy and then more heavy and red in colour and continued until 14th jan. Now I was due to start my cycle on 29th jan. That did not happen. Please advise.
