Overview of NuvaRing (The Ring)

The NuvaRing is a combined estrogen/progestin ring that is inserted into the vagina and left in place for 3 weeks, then removed for a 7 day ring-free period to permit withdrawal bleeding. Requires a visit to a healthcare provider to get a prescription and a visit to a pharmacy to get medication. 

How It Works

The hormones prevent the ovaries from releasing an egg (ovulation) and the progestin thickens the cervical mucus, which helps to prevent the entry of sperm into the uterus. The NuvaRing can be removed for up to 3 hours (e.g. during vaginal sex), but if it has been out for more than 3 hours, it should be reinserted and a backup method (such as condoms) should be used until ring has been in for 7 consecutive days.
