Hello, I had protected sex on 1st march but we thought there was a condom issue, so after 3-4 hours, i had the ipill. On 11th i had slight abdominal pain and had light bleeding which looks to be very less than what i have in my normal menses. This bleeding ended on the third day(i have 7-10 cycle usually). My next cycle  is due next week. Is this ia something i need to be worried about and take a pregnancy test to confirm? I also did a home pregnancy test and it was negative. Thanks in advance.
