Ethinyl estradiol / levonorgestrel
"I've been on Aviane for a month now and have no complaints really. It's been great for regulating my periods and providing protection from pregnancy. My period was normal, and I haven't experienced any major weight gain (gained a 1lb or 2) or loss. My breasts are tender sometimes, and I've experienced some  swelling. But I'm not complaining about the free breast job. The only thing that has been a bit annoying is that my sex drive has increased, and my libido was high enough to start with. Other than that, it's a great contraceptive that I plan on taking it for a while."
