White Pill, Had unprotected . (Help?)?

Hi i am also on yaz and i always get my period the last day of the white pill or sometimes the 1st day of my new pack. i would wait it out another day or two if she doesn't get it then you might want to be worried but skipping a period when you first start birth control is not uncommon. It is not likely that she's pregnant because aside from birth control being 99% effective it is very unlikely to be ovulating around the time of your period anyways even without birth control. women usually ovulate about 12-16 days after the 1st day of your last period. good luck =]
