She took a pill after we had sex, and having sex until she got her period we got worried, so she took another pill after a week ago from the other, and then we had sex again between the week and a half and she hasn't gotten her period. We used protection everytime between each week but it was spermicide and she hasn't gotten her period in 2 weeks and a half from the first pill or 1 week and a half from the second pill. Should she take another pill to insure she isn't pregnant.
