How does Annovera work?

Last updated on August 31, 2020

Annovera is a combination hormonal birth control that is inserted for 3 out of 4 weeks every month. It contains a year's worth of hormones, so there’s no need to get a new ring from the pharmacy each month. You leave it inserted for 21 days and remove, clean, and store it for 7 days.
