You take the pill at the start of your period and and it will stop pretty soon after. Mine did. But if you start taking it you will have to carry on taking it until you want a baby.
It's no hassle though and so far, I've got mine free.
If you forget to take it one day, just take 2 the next day, the effects of missing one or stopping for a week don't really kick in for around 3 days and the side effects vary from person to person.

I know I've atually lost weight and grown a bigger chest while on the pill :P
