"i have been taking yaz for 8 months now and am very pleased with the results.  i have not gained any weight, my acne cleared up completely, and my periods are shorter and lighter.  the first three months i did experience side effects; migranes, tiredness, breakthrough bleeding just the first month; but other than that, it was fine.  i attribute those first three months to my body getting used to the hormones.  at first i was hesistant to try this birth control because of the horror stories i have read online, but i decided to try it anyway, and i am so happy that i did, because it has been wonderful for me.  i suggest anyone debating on trying it out, to not be discouraged by the reviews, because everybodys body is different."
