You posted this awhile ago and am not sure what ended up happening or you. Come back and update us. In general, ECP is for emergencies only. Taking it more than once or twice a year is taking it a lot. It's a huge dose of hormones which is how it works to prevent conception/pregnancy. And it has to be taken within 72 hours of the sexual intercourse you are worried about. So, with that said, when you had taken it and had sex that day you took it, it would work for that event as well. So, you should be good and did not need to take another dose. Have you been able to get on some type of birth control?
