Most of the pills I've seen like that are birth control pills too. The thing to remember is that the "periods" that one has on birth control pills aren't really periods at all. They're withdrawl bleeding. You can get the same results as these new fewer periods a year pills by skipping the 7 dummy pills in traditional birth control pills cycle. A lot of OB/GYNs have been having their patients do that for years. The main downside to these pills, beyond the side effects and risks associated with ANY kind of birth control pill, is that should there be a failure, you wouldn't know as soon. You'd have to rely on breast tenderness, morning sickness, fatigue, etc, to let you know you were pregnant. Of course, since those can also be side effects of the Pill it gets tricky.
