Ethinyl estradiol / norgestimate
"I have been taking TriPrevifem for about 7 months now and no complaints whatsoever. After the second month of taking Tri-Previfem my period has definitely done a 360* and regulates monthly now. I haven't felt on edge and I have lost weight as well as going down a cup size on my breasts. It's a great pill, but know the tablet can vary in side effects depending what your body can handle. FYI: definitely research on your own as well as talking with your primary doctor!"
