How does the nuva ring work?

Answers:

It stays in you all month, collecting bacteria. I wouldn't run there. Here is what the Nuva Ring site tells you:
NuvaRing(R) contains 2 types of hormones: estrogen and progestin, which work together to prevent your ovaries from producing mature eggs. These are like hormones found in the Pill, and they work the same way surrounded by your body even though they are administered differently with NuvaRing(R).

With NuvaRing(R), hormone release is activated once the ring comes into contact with your vagina. The hormones are next absorbed and distributed into your bloodstream.

When used as directed, NuvaRing(R) works as well as the Pill—it is 99% effective within preventing pregnancy.
NuvaRing(R) works with your cycle

Over the course of 3 weeks, NuvaRing(R) releases a continuous low dose of estrogen and progestin. Higher estrogen and progestin levels signal your brain not to release the hormones that cause egg maturation. Without an egg geared up to be released into the fallopian tube, ovulation cannot occur.

A few days after you remove NuvaRing(R), the lining of the uterus begin to shed and you get your period.

Your new cycle begin again on the 29th day, which is the first day you insert your new ring after human being ring-free for a week. It is important that you insert your new ring on the same afternoon of the week each month. Source(s): http://www.nuvaring.com/Consumer/aboutNu…
