The contraceptive patch is a small, thin, square (5cm x 5cm) and is beige in colour.  You stick the patch on your skin and replace it every week for three weeks (21 days), then stop using the patch for seven days (patch-free week when you will experience a light breakthrough bleed).  This is called a patch cycle.

The patch releases two hormones – estrogen and progestogen which are similar to the natural hormones that women produce and are like those used in the combined pill.
