Do you still have a period while on the patch?

No, you don't want to wear the patch during mestruation. However if this is your first time using this method of Birth Control and you chose to do a "Sunday start" then you will apply the patch on the first Sunday after you have started menstruating. This is ok if you are still "bleeding" because your body will eventually even its cycle out. Your doctor should be able to help answer any other questions or go to: www.orthoevra.com
