I haven't been on oral BC in about 8 years, but when I was, I was really prone to headaches due to the "withdrawal" of hormones during the 7 days of no pill/placebo. So my doc put me on the progesterone-only pill, Ortho-Micronor. Before that, I was on Tri-cyclin (sp?) but that was the one that gave me headaches. They both seemed to be great for BC though!
