"i&#039;ve been on trinessa for 5 years. age 17 to 21. my doctor prescribed it for hormonal acne i had. i also use it for birth control and it has worked perfectly. the first two months i had mood swings, which is to be expected when putting hormones into yourself. i went up two cupsizes. i didn&#039;t notice it clearing my acne for about 2 or 3 months but it&#039;s worth the wait. i do still get cramps but nothing a motion can&#039;t fix. my acne is still present occasionally, but that is definitely due to genetics. the pill makes my periods extremely regular and accurate, which is great. i get them the fourth wednesday of every month always around 10-11am. i would recommend."
