More About the Ring

  • The Ring is a small, flexible ring that you put in your vagina.  You need to replace it every month.
  • The hormones in the ring stop ovulation and thicken cervical mucus, which blocks sperm from getting to the egg. If sperm can’t get to an egg, you can’t get pregnant.
  • Because the hormones in the ring are the same ones that are in the pill and the patch, the benefits, limitations, and side effects are similar.

How to Use the Ring

The ring lets you control your period. If you want a regular, timed period, keep the ring in place for 3 weeks. Take it out on the fourth week and that’s when you will have your period. After 7 ring-free days, put in a new one. Store your unused rings at room temperature and out of direct sunlight.

You can also choose to skip your period by keeping the ring in for the whole month. Either change it the same day of every month or wear it for 28 straight days then change it.

  • With clean hands, squeeze the sides of the ring together and push it into your vagina – it’s like inserting a tampon. It should be comfortable.
  • When it’s time to take the ring out, hook your finger around the side and pull it out.
  • Wrap the used ring up and throw it in the trash, but don’t flush it down the toilet!
