I'm always timely about taking my birth control. So this is new to me..But last night when I went to take my pill I realized that the day befores pill was still in the pack. I panicked because I wasn't sure which day I had missed so I went to my local pharmacy in picked up plan B, even though in hindsight I feel as though I may not have needed to, but my question is how long till I am protected from pregnancy again? I am going to continue taking my birth control today as a normal.
