Tri-Previfem
abnormal uterine bleeding
"My insurance company just switched me from Ortho-tricyclen to Tri-Previfem. This is my second month on it. My period usually lasted for 3 days also. This time it's been 5 days. And in the past 2 days, I've had a lot of bleeding. I've gone through over 10 pads already today. I will stop taking it and try to go back to Ortho Tri-Cyclen. I'd been on Ortho Tri-cyclen for many years and never had any side-effect."
