"I have had a terrible experience with Gianvi. I have never had problems or side effects with any other birth control before. Gianvi gave me severe migraines. The migraines would be so bad I would stay in bed for days. Gianvi also messed with my vision. After taking it I started having blurry vision. It also caused me to have mood swings. I cried over anything, including commercials on T.V. After finally realizing it was Gianvi causing all of my problems my husband and I decided it was best for me to stop taking it. Best luck to any one who takes this."
