Birth control vaginal ring

What is a Birth Control Vaginal Ring?

This is a form of hormonal birth control that is inserted into the vagina and left in place for several weeks at a time. The vaginal ring releases a combination of estrogen and progestin hormones, which prevent ovulation and thicken cervical mucus to prevent sperm from reaching an egg.

Examples of birth control vaginal rings include NuvaRing and Annovera. Vaginal rings are a convenient and effective form of birth control, but may cause side effects such as headaches, nausea, and vaginal irritation.
