I missed two pills sat and sun the 25th and 26th of April and started taking one pill a day again starting Monday (27th). I had unprotected sex 8 days later (Tuesday May 5th) where my boyfriend ejaculated in me, is there a chance I might be pregnant? I also decided to use my pills as an EC by taking 5 in two doses 12hrs apart and the first dose was about an hour after the intercourse, is that effective enough to have stopped any change of pregnancy?
