"i&#039;ve been on trinessa for 9 months now and it is fantastic. before starting the pill i had pains from my period that would have me in bed and crying for days. it took about 3 months for the pills to really take effect, but i noticed a big change in how much pain i was experiencing. i could make it through a day of school just by taking a midol in the morning. now my periods last for no longer than 4 days, they&#039;re on schedule, and they&#039;re all but painless. i have gained very little weight and my skin was mostly clear even right before i was about to start my period. i have missed two pills in the 9 months that i have been taking them, but i can&#039;t say i was overly worried about it. i highly recommend this pill for pain and birth control."
