"i&#039;ve been on different birth controls for 6 years. always on a low dose and i will say i&#039;ve always had accuracy with all . after getting tests done even at 15 i&#039;ve been told i&#039;m extremely fertile. not once did i get pregnant until at 17 i stopped for a while and i had a miscarriage. but not once taking the pill. every month almost i become paranoid it will fail but has yet to. i take the pill around the same hour almost every day and if i miss one i double up. i get nauseous for days after so i assume it could be pregnancy. this makes me use the internet that entire month looking at pregnancy signs and reading scary reviews about women saying birth control failed them. i believe that is only because they haven&#039;t been taking it right"
