I have been on Quasense for 4 cycles, (a full year ) The first two no problems, the three a little breakthrough bleeding but only lasted two days or so and stopped. Now that I'm on the 4th cycle, bleeding everyday! I thought this was suppose to be helpful not an inconvenience. I am so confused and frustrated. Why now after a year of no problems? But After reading some of these posts I have noticed very severe mood swings and uncontrollable emotions. Crying a the drop of a dime. This stuff is evil!
