"i started taking birth control at 18 years old, i am now 25. i was on ortho-tri-cyclen for about 5 years, did great on it. due to insurance i had to switch to trinessa, heavier periods and more mood swings followed. now the pharmacy gave my tri-sprintec because they don&#039;t carry trinessa. i am on day 8 and am getting more nauseous by the day. the pharmacist assured me that trinessa and tri-sprintec are the exact same medicines, just made by two different manufacturers, but i have never felt so nauseous in my life. i know pregnancy is not even a consideration because my period just ended the week i started taking the tri-sprintec. i will be switching back to trinessa next month, no matter the cost! hope this helps someone with similar situation!"
