I was on Yaz for probably two years, and stopped taking it around August of '09. In late September/early October I got a light period, and since then have not had one, and it is almost January. I know they say it takes up to 6 months for your period to come back sometimes after quitting birth control, but is it possible that my not having a period is due to quitting birth control this year, even though I HAVE had ONE since I quit?
