"i&#039;m almost finished my first pack of trinessa and the side effects that i&#039;ve experienced are lots of bloating and also vaginal discharge. i&#039;ve gotten use to the bloating, but the vaginal discharge is annoying and frustrating because i kept thinking it was a yeast infection or something like that and everything i&#039;ve taken to try to get rid of it has not worked and it was driving me crazy, but after reading some of the reviews for trinessa, i realized it must be one of the side effects of the pill because it started when i started taking it. the first week i started the pack, i had a lack of appetite, but i&#039;ve been eating regularly since then. i haven&#039;t experienced any weight gain. overall trinessa seems to be a decent birth control"
