Took I pill on 28 th dec * ( unprotected sex on 27 th ) , after completion of period cycle on 25 th dec But after the Intercourse on 17 th Jan I had bit of spotting due to hymen breaking ( which was not done in previous attempts and I had rough Intercourse as well ) then on 18 th Jan I got bleeding which was not like periods as there were no cramps and it was light as well not heavier that got ended within 3 days Does withdrawal bleeding can come even after 20 days of taking I pill if not what kind of bleeding was that
