"i&#039;m 19 years old, and i&#039;ve been taking yaz for about 2 years or so. at first, it helped clear my acne but made my pmdd worse, but eventually my moods evened out into a constant apathy, and my acne began to come back (possibly because of stress). i&#039;ve lost weight and noticed an increase in breast size, but my sex drive has completely died out within the past year or so. i feel stressed when i don&#039;t take the pill on time or whenever i stop taking it for the four days allotted for my period (during which my period doesn&#039;t arrive until at least the third day and last a couple days into the new month of pills). but my period is light and relatively pain-free."
