sure there are...it's just a matter of trial and error until you find the one that works best for you...we're all different you know! The one I'm currently on is Mircette...it's 28 days per pack...in a lot of birth control pills, they give you 3 weeks of pills with hormones, and the last week of pills are placebos, or "reminder" pills...there's no hormones in them, they're just meant for you to take them so you don't forget and fall out of the daily habit...Mircette has a bit of estrogen in the last few pills of the pack (which would be when you're actually at the end of your cycle)...the added estrogen seems to be helping the headaches...I used to get migranes so bad I could only take a prescription and go to sleep to feel better...now I'm down to 1 headache in the past 4 months...a great track record for me! :)
