"i&#039;ve been on tri-nessa for about a year. but i have had one pretty serious side effect, vaginal discharge. i honestly did not think about it being a side effect when it started. i went to my doctor and they treated it as a yeast infection but nothing helped. my doctor told me i was just one of the few women that had regular discharge. now that i have been off of tri-nessa for only a month, the discharge has stopped. i am now going to try and change medications."
