Its the absolute worst. I had been on Yasmin for 2 years and my Dr. switched me to Femcon. I cant even explain. After two years I finally felt like myself again. Yasmin gave me crazy head ached, anxiety, and intense emotional moods swings for no reason. My friends though I was loosing it. Now Ive been on Femcon for 6 months and its amazing. Theres no weight gain, MUCH better skin, and no breakthrough bleeding. I think Femcon is the miracle pill! Plus my breast grew one full cup size with no weight gain. : ) I'm telling you its a miracle!
