Migraines and birth control

I was on the pill ortho tri cyclen lo for 4 years and always suffered migraines. Sometimes 2 or 3 times in one week. I didn't realize it was from that. I haven't been taking it now for 5 months and relying solely on pull out with my boyfriend. We just can't do condoms and I refuse to feel uncomfortable during sex for the sake of not having a baby. If it happens it happens. But I was wondering if anyone found a birth control that didn't cause them migraines.
