headaches?

This is my 5th month on yasmin and I must say I feel great! I have been losing weight and fast since I switched to it and no other birth control did this for me. Ive lost 30 pounds since I started it. This is my first low dosage pill in 10 years. My first couple of months were tough because of terrible headaches and I know it could have just been because I wasnt used to lower dosage. My sister in law just had to quit yasmin because it caused her to have migranes during her period and it gave her terrible cravings and she gained weight. This pill remains a mystery I guess. It just does so many different things to different people. Id love to hear more comments. Please let me hear what it did to you.
