Scarleteen

I am on the birth control pill and have been since about May of 2015. I have never missed one pill! But Tuesday, the first of december, i was trying to take my placebo sugar pill and it acidentally fell down the sink.. I am quite concerned and nervous. What do i do?

The placebo pills are optional: some people take them, others just take seven days off of their pills without taking those pills. They aren't active pills with any medication in them, so it's no big.
