Birth control for teenage daughter?

What will you be putting your daughter on and when? Before she starts sexual activity? After she gets her period? When she gets her first boyfriend?

And what will it be? I feel like even as an adult, I'm not responsible enough to take a pill at the same time each day, and I would hate to have her slip up. But it also seems invasive to get her an IUD or to have the rod inserted. Any advice or experience is welcomed!
