My doc. recognized PCOS. I have always had irregular periods, after by second child delivery my period stopped for 24 months. I was on NORA -BE during nursing my baby (12 months), after that on YAZZ. None of them caused my period apperied. Since 3 months I gained 10 pounds. My doc. prescribed ORTHO TRI-CYCLEN but I am affraid, cause I heard many of women gain weight.
