Situation: 25th January, it's the 5th day of periods - had unprotected sex during this 5th day period, took an ipill within 24hours. My periods ended on 27th Jan. On 28th Jan, had protected sex but the condom broke and since I wasn't sure how long the previous pill lasts, i took another ipill on 29th Jan. Feb 2nd: i started bleeding, it's like regular periods and now it is the 4th day of this bleeding. What does this mean? why am I bleeding so soon after my period just ended? is it because of the pill or is it pregnancy? please reply, i took a pregnancy test but no lines were shown and now I'm even more confused if it is because of invalid test or something else.
