birth control
"I've been on Trinessa for almost a month now. I'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'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't so bad. I highly recommend it to anyone!"
