I take the pill so im not really educated on the patch, but id just wait it out, try not to stress because it can make your period come even later, if it doesnt come within a week, try taking a pregnancy test. :)

But but.. Im only 18! Pray i'm not. Lol thanks for your help though!

Try not to worry, you usually dont get your period for upto 3 days after taking the patch off.
I take mine off on a monday and I usually get my period wednesday night, if this is your first time using it take that into account as your body is adapting. :wink:
