How does nova ring work?

The NuvaRing is a hormonal contraceptive device that is a flexible ring inserted into the vagina. It releases a combination of estrogen and progestin hormones over a three-week period to prevent ovulation, thicken cervical mucus, and thin the uterine lining, thereby reducing the chances of pregnancy. After three weeks, the ring is removed for a one-week break, during which a withdrawal bleed typically occurs. It is effective when used correctly and offers a convenient alternative to daily pills.
