It really depends a lot on what pill you are taking. Multiphasic/monophasic, high/low dose, combined/progestone only...all these make a difference.
When I was taking a combined pill, the window they suggested was 3 hours, but if you're on a low dose, it might be a smaller timeframe.
The ones I pity are the ones who never stick out their neck for something they believe, never know the taste of moral struggle, and never have the thrill of victory. - Jonathan Kozol
