Hi I am 21 years old and on Trip Sprintec for the first time, I missed, well not missed but I took my pill late the last couple weeks, I started BC May 4 and that Friday I did not take it until Saturday, I double dosed and the following week I took my BC late again but took it asap, and this being the 3rd week I took it again late, will I be okay? No pregnancy chance? I also am concerned about in the future being able to get pregnant, I have not had any other birth control before besides taking Plan b , I was wanting to be sure that if I do stop taking this BC in the future will I have trouble conceiving?
