"i tried trinessa for a month and a half. it was the first birth control i had ever taken but it was the worst. my mood swings were off the charts. i don&#039;t think a day had gone by for me without crying and/or having intense mood swings. i have recently switched to yaz and i love it. yaz is a good switch from trinessa if you&#039;re having problems. it&#039;s a lower dose of hormones with the same effectiveness. i can honestly say i feel like a better, happier person on yaz. plus i have pmdd. so it has helped out greatly for moodiness. my boyfriend and i can actually hang out without fighting for stupid reasons that were just plain ridiculous before."
