Ethinyl estradiol / etonogestrel
"After two years on the pill, I decided to try this product as my method of birth control. 

Pros: 

- You don't have to remember to take a pill every single day

- You can't feel it when it's in

- You partner won't really feel it during sex after a few times

- It works! I have even left it in for up to four weeks to prevent my period from starting during an important event or a vacation

Cons:

- You may be very dry. I'm not sure why but even when you are aroused it is difficult to "self lubricate." But that's nothing some lube won't fix."
