I am panicked with the thought that I may be pregnant and could really good use some advice. I was on lutera for about three weeks and then got a short period 3-4 days pretty light, on Mar.1, I still had active pills and kept taking them, till I thought I should stop and let my body have a period. I waited about 6-8 days before starting a new pack and had unprotected sex on the 11th. I used lutera as directed for emergency contraception 24 hours from the time of unprotected sex.I have used lutera as emergency contraception in the past and know that I need to take it regularly to be fully effective against preventing a pregnancy, I am just nervous because if I had a period on the 1st would I be fertile on the 11th, or with being on the pill previously is my body less fertile. Any advice is appreciated.
