"i have been on ortho tri cyclen for almost nine months. i had to switch from ortho tri cyclen lo because my insurance no longer covered it but i had zero problems with that birth control. within the first three months of ortho tri cyclen, i didn&#039;t notice any significant changes, however, over the last six months i gained 9 pounds. my weight has been consistent for the last six years until i started this pill. other than weight gain, i haven&#039;t had any major issues but i will be switching pills due to weight gain."
