While this is a great general overview of the way oral contraceptives work, I couldn't tell how Apri is different from other OCPs.

A very informative page on the Apri birth control pill. This page covers uses, side effects, warnings, interactions and more. This page is easy to read and very educational.

Maybe it's just me, but I couldn't make this page show me anything other than a standard "don't smoke" warning.clicking on the other tabs got me jumped to the bottom of the page.
