i have been of the patch for 5 months now and im trying to get preganant
i think that the medicine in your body is not effective any more than 12-24 hours after you take the patch off. i wouldn't take any chances. if you're looking to become pregnant, i wouldn't be surprised if your body evens out its natural cycles without the hormones in a few months or less. but as far as the contraceptive being effective, you need to have a patch ON YOUR BODY or be on your off week, otherwise you're playing risky.
