Well I have looked at a lot of web site for information about birth controls and this one by far seems to be the best. I'm 22 years old and have been on and off birth control since I was 15. So far every one I have tried has caused either nausea or Sever Break through bleeding. Last November I decide to give the depo shot one more try, for the first month I had no break through bleeding. But in December it started and never stopped, here it is April 30 and I experienced maybe 5 days during my duration of the depo shot no bleeding. So I went to the doctor today because I have come to realize that my body may need a higher dosing of hormones so she prescribed Femcon. Now in the past I have had the same problems that have been posted on here but when I was not on birth control! Birth control, controlled my symptoms a little but never stopped them. So im hopping that Femcon control that awful breakthrough bleeding I experience with many other contraceptives. At the end of my pack im going to update! Todays day 1
