I started taking Yaz 4 yrs. ago after the birth of my daughter. I thought I had postpartum & began taking Lexapro too. Then I gained weight almost 40 pounds. My doc. thought the Lexapro stopped working & prescribed Cymblata. I stopped getting my periods & when I did have them I was crampy & irritable. In addition, I was experiencing menstrual migraines. Decided to change my pill. Now 3 weeks. exactly on another BC & I'm a NEW WOMAN. Too bad I lost my marriage in between as a result of my eratic/psycho behavior. I read this could cause respiratory symptoms too...I always have sinus infections I contributed to where I live. I HATE YAZ. It has wrecked my life!!!
