"i started on trinessa 7 years ago, i had no problems whatsoever! it actually worked very well! because of changing insurance companies i had to change pharmacies and i could only receive trisprintec. the pharmacist said it was the same thing..although it was a pill 3x bigger. i don&#039;t believe it was the same dosage. anyways when i first took the pill i noticed from the first day i was nauseous. i ended up quitting my birth control cold turkey on the 6th day of the pack because i couldn&#039;t stand the nausea, headaches, and hot flashes. since i&#039;m planning on starting a family here in a few months i am just going to stay away from this birth control method. i would not recommend this medication..although everyone is different. just not for me."
