"i took yaz for 4 yrs and absolutely loved it. first, yaz doesn&#039;t make you retain water, so when your period comes you never feel like a typical bloated boat walking around. definitely helped with lighter, shorter periods. i&#039;ve never had acne, but yaz definitely cleared up even the tiniest pimples. you should still expect a few around your period but nothing crazy at all. the only bad side effect i would say was, sometimes it can make you a little crazy. you can become a really emotional, angry hot mess. i switched to another birth control because i was sick of taking the pill everyday. however, i would definitely recommend this."
