I had unprotected sex on the sixth day of my cycle and within two hours, consumed an iPill. Six days later, I had another period for 4 days. There was a gap of 11 days between those two phases of bleeding and I had two periods that month. I am already pretty late for my period this month and I took a pregnancy test one day after the day my period was due which came to be negative. Could I be pregnant regardless and should I take another pregnancy test?
