Lybrel is a new, continuous low dose oral contraceptive with NO OFF WEEK AT ALL. That means: no periods at all. It's not dangerous to forego a period when you are on the Pill because your lining does not "build up" and back up on you or anything and having a period while on the pill is more of a cultural thing than anything.
I cannot believe how many stupid newscasters kept asking their in-house doctor correspondents about this today. It's pretty common knowledge among women, or so I thought. The really fabulous news is that within 3 months of going off of this pill 99% of women were either pregnant or at least ovulating. So, that's good news. However, this tells me that no women with anovulatory conditions (like mine) were included in the study trials...or were they and this cures them? No, they probably weren't. If I were making the trial, I would include women who were healthy, non-smokers who really did not want kids now so they would be good about taking their pills and making my numbers look good.
