I was the one who mentioned the NuvaRing.
It's essentially a little flexible, clear plastic ring, only 2in in diameter, that you basically insert and leave for three weeks. It's low dose etonogestrel/ethinyl estradiol and they say it has advantages over pills because the hormone level is constant in your body.
Another advantage is that you don't even know it's there, as opposed to having a patch on your butt! I usually take it out for sexual activites only because i found it to be uncomforable, but i guess it depends on each person.
I've never been on any other type of birth control, so i'm kind of biased about this one!!! <img src="i/expressions/face-icon-small-smile.gif" border="0"> but it beats the heck out of having to take one more pill everyday. I think the website it www.nuvaring.com if you need more info.
Hope this helped
