birth control
"I was on Trinessa when I was 18 for about a year, and it worked fine for me. I then discontinued use of any form of birth control for for several years, but at 24, I decided to get back on the pill. I figured I would go back to Trinessa since it worked well before. I've had a history of irritable bowel syndrome ever since I was a child, and finally got it under control at around age 21. The first time I was on this pill at 18, it didn't affect my bowel habits. But something must have changed with the pill or with my body, because from the day I got on this pill last month, I've been having irritable bowel flare-ups DAILY, literally unable to leave the bathroom for an hour."
