on my third pack now...for the first week when i started i did feel very tired, sleepy...and lazy, also had some light headaches..but that all went away.
did not have any mood swings, actually i am less cranky and in better mood.
before starting on BC... i had severe pains, long periods ( 6 days) and really bad bloating (would go up a dress size)...
so far Yaz has been good, no pains, light periods. period usually starts on the 4th placebo pill. the only problem as soon as i start taking placebo pills i get red bumps that sort of look like pimples on my face... and they last me until i am done my period.
