This was my first time. I've been on the pill for about three months now. This is the first week after my period so its a new pack and I have been taking it at the same time each day for the last week, it is Friday. He switched out the condom about halfway. He cleaned up and then applied a new condom and we continued. I can be a very paranoid person so my question may seem ridiculous but even with proper use of duel protection, should I take a plan B pill?
