I've been on the birth control called Trivora and the last time i needed a refill, the drug store didnt have trivora in stock, so they gave me Enpresse, telling me that its the same thing and not to worry. All week I have been unusually sick to my stomach to the point of almost puking and extremely moody and I'm wondering if that has anything to do with it? If you could respond that would be great. Thank you for your time!
