If you miss one, take two the next day, like hales said, but if you miss two in a row, your body will start getting back to normal and ovulate anyway, so don't take three or more at once. It will screw up your natural rhythm. If you miss two or more, take ONE as soon as you remember.
Well, i'm on birth control and my doctor said if i miss one, take two the next day. Are you missing them all at once? If so, it could make you ovulate.
It makes your chances of getting pregnant far more likely. You need to take it at the same time EVERYDAY in order for it to work correctly.
