The ring prevents pregnancy by transferring hormones into your body through the surface of the vagina. This method uses a 28-day cycle. A ring is inserted and left in the vagina for 3 weeks (21 days). The ring is removed after 21 days and your period should start during this ring-free week.
There are three options for starting the Ring:
Remove the ring three weeks after insertion on the same day of the week it was inserted, about the same time of day. Remove the ring by hooking the ring with your index finger and pulling it out.
After a one-week ring-free break, insert a new ring on the same day of the week it was inserted in the last cycle. For example, when the ring is inserted at 10 p.m. on Sunday it should be removed on the Sunday 3 weeks later at 10 p.m. Do not leave the ring out longer than 7 days. It is a good idea to check ring placement every day to be sure it has not slipped out.
Abstain from intercourse or use an additional method of birth control such as a male condom if you have intercourse during the first 7 days of this cycle.
