I have been on Lo Loestriñ Fe for two weeks now. I just had sex with my boyfriend and he came inside me. I take the pill everyday at the exact same time; haven't missed a pill and hasn't been late. And I took the first pill on the first day of my period. I have a couple questions: first, am I going to get pregnant? How long does it take for the pills to become effective? I want a clear yes or no, please. And second, could I get pregnant during the brown and white pills? And if I don't take the brown pills, is that going to effect my cycle? Please answer everything as possible.
