I LOVE the NuvaRing. I had side effects from the pill but the NuvaRing has less than half the amounts of hormones that the pill does so it has been a *great* option for me.
You insert it (the placement doesn't matter at all) and leave it in your vagina for 3 weeks, take it out, have your period and then put in another one for 3 weeks. You can also do what I do and leave it in for 4 weeks and not have your period at all
Here is a link to it and you can also compare it to other methods of birth control, it also shows the hormone dosage so you can see how much less it is than the pill:http://www.nuvaring.com/Consumer/index.asp

Besides the NuvaRing that I have had experience with a have a few friends who love their Mirena IUD's. It is also very very low hormones, no estrogen. The Patch is a good choice as well.
Good luck. I just hope you find something that works well for your body and lifestyle.
