"i&#039;m 20 years old and this is the first birth control i&#039;ve ever been on. i&#039;m in my 3rd pack and so far i haven&#039;t had any serious side effects. when i first started my appetite was out of whack and couldn&#039;t really eat and i was really moody. but halfway through the first pack that subsided and i was fine. i never had a real problem with having a heavy/irregular period but when first going on this i got my period twice a month for the first 2 months but they are very light, short, and manageable. not sure if i gained any weight because i don&#039;t weigh myself often and i don&#039;t think i&#039;ve seen a real change in my body. i just changed my diet and exercise regiment (as in i&#039;m actually exercising and eating better) so hopefully i&#039;ll see results!"
