Will the patch work if you put it on during ovulation and will it stop your next period and would your period return when you removed the patch?

Yes it will work and yes it will stop your period from coming.I've done it many times.When you do decide to take it off you will have your period as if you would normally taking it off every 4th week.I've done it stopping my period up to 2 months,but sooner or later your period will come even if you keep putting the patch on if you putit off for too long.
