I'm glad others agree having no period is not natural. All the girls they show on the news say "it's just great!" Well I started this for a different type of pill, but now I'm questioning my regular pills, Ortho Tri-Cyclen Lo. I have always been on pills with the excepting of a few months on Nuva Ring, but it was too expensive with no med insurance. I don't have any difficulty with these pills, and have heard they prevent certain types of cancer. It is just the easiest, least expensive method for me. When you say it messes up horomones, in what way? Like mood swings, or something medically wrong with her body?
