"i&#039;ve been on trinessa for almost a month now. i&#039;m 18 and ever since i was 15, my periods have been outta wack! i skip 3 months at a time with no period. my doctor put me on trinessa and so far i haven&#039;t had anything wrong! the only thing is i hate the placebo pills. my period has been terrible! i have terrible back and stomach cramps, but my bleeding isn&#039;t so bad. i highly recommend it to anyone!"
