I have a couple suggestions. I was with a girl that hated condoms also, but she wouldn't take the pill.
I ended up switching from latex to lambskin. It's more expensive, but definately worth it. It keeps the little guys from reaching the egg, but does absolutely nothing against STD's getting to ya peter. So be sure you absolutely trust the person you're using them with. I'm guessing that you already do since you're "pulling out" *smh*.
If that still doesn't work for you there is a spermicidal cream that she can use before you guys have sex. I've personally never used it, but I see it in the condom isles everytime I go shopping.
Then we have the diaphram. Little thingy that gets stuck in her poon that keeps the little guys from reaching the egg. I've seen these things before, but I'm not sure if it's something that she can insert herself, or the docs have to insert it.
If you're just set on the pill, then you can tell her that it will clear up her acne, make her period less heavy and possibly less frequent.
(I sound like one of those commercials huh? Tell you all the benefits of doing something, then say "Taking this drug may cause, diarhea, bloating, upset stomach, and possibly DEATH")
Good luck
