I have been on ortho for a few months now. I never experienced headaches when I began it though.
If this is your first time on the pill, it could be your body adjusting to the hormons. Most doctors will tell you to stick with one pill for 3 months as to give your body the time to adjust.

When in doubt, call your doctor-good luck!
