How do I use it?
The vaginal ring is easy to use. Squeeze the ring between your thumb and index finger and gently push it into your vagina (the exact position inside the vagina is not important). Use back-up birth control (like a condom) for the first seven days after you insert the vaginal ring.
It is important to pay attention and keep track of when the ring is inserted and removed. Leave the ring in place for three weeks (21 days) and then remove it for one week (seven days). Your period will occur during the week the vaginal ring is out. After the off week, just start over and put a fresh ring in for three weeks.
You can leave the ring in place while having sex. If the ring falls out for any reason and you are not able to put it back within three hours, another birth control method will be needed until the ring has been in place for seven days.
How do I get it?
You need a prescription. The vaginal ring can be purchased at pharmacies and clinics. It is sold under the brand name NuvaRing.
