The vaginal ring is a contraceptive device inserted and left inside the vagina for three weeks, during which time estrogen and progesterone hormones are absorbed from the device. Your doctor will try to find the most effective, lowest dose and use it for the least possible time to prevent side effects.
In the first cycle of Nuva Ring, you can put the ring on the first day of your period for immediate protection from pregnancy. You can put it in any other day of your cycle as well, but then need to use a back up method (like condoms or abstinence from vaginal sex) for seven days. In later cycles using Nuva Ring, you put it in on schedule, a week after you took out the last one, on the same day of the week that you took the last one out.
