I want to go on the pill and i am 16 years old but i wondered how long it took for the pill to work and before it would be effective?

How it works: The pill hormones work by tricking your body into believing you are already pregnant, so you don't release an egg every month. (saving them for later) Some pill promoters say you are protected within a week or two.Most providers would encourage you to use a backup BC for at least a month to be sure your body has adjusted to the process.
