Ethinyl estradiol / etonogestrel
"Overall, I've had quite a wonderful experience with NuvaRing. It's very easy to use and it's very effective. It's perfect for those who are incredibly busy or have an unstable lifestyle (college students, bride-to-be, constantly changing work schedule), and I've had very minor side effects. Let's start with the positives though - regular periods that are very light, almost perfect skin except when on the period, no hair loss, no mood changes, and no weight gain. It's also very simple to get off the ring and switch to another birth control or completely stop birth control all together. The two side effects that I've experienced are low libido and I get headaches a lot easier. I can also feel the ring during sex but that's an easy fix."
