Choosing birth control

My boyfriend and I have been together for a while now and I think I'm finally ready to have sex. I am 16 years old and I don't want to have to worry about taking a pill at the same time every day because I tend to forget about that kind of stuff.

What type of birth control do you suggest ?

Also I suffer from migraines and don't want something that could make them worse or more frequent.

help?
