Ethinyl estradiol / norgestimate
abnormal uterine bleeding
"I have been taking Ortho Tri-Cyclen for about 6 years -- then my insurance switched me to Tri-Spintec. Then a couple of months after that I was switched to Tri-Previfem by my insurance. My period last month was so light, I was thinking "yay!".. but I'm halfway through my pack this month and have started my period again. I'm going to guess it will continue into next week when I'm scheduled to have my period. I don't like this at all. Part of the reason I love birth control is I can be in control of my period and schedule things around its arrival (i.e., my wedding coming up). After reading these reviews, I'm going to talk to my pharmacist about going back to Ortho Tri Cyclen. Thanks for the reviews ladies."
