I'm on BC pills and sexually active. I haven't missed a pill and they have been taken on time. I noticed I did not have any sticky discharge during my cycle and my period is coming up soon, is that because of the pills? Recently, we have used the pull out method instead of using back up protection of condoms. We had sex twice in one day, he did not go in me but should I be worried from residue in the second pre cum? Should I be concerned about pregnancy considering I have not missed the pill?
