"after trying practically every birth control on the market and having horrible side effects, i&#039;ve finally found zarah! the first month of taking it i had a couple of side effects, which were bad mood swings and constipation. but i waited it out and sure enough, once i started the second pack, all those side effects were gone. i now have 3 day cramp free periods and the clearest skin i have ever had in my life. i highly recommend this birth control, but remember: give it at least a month!"
