I tried Yasmin for about 4 months last year, after being on Ortho for years. My doctor prescribed it after I mentioned weight gain (about 5 lbs) on Ortho. While on Yasmine I started having serious stomach issues including severe constipation and stomach aches, to the extent that even over-the-counter laxitives did not help and I was very uncomfortable. Once I woke up in the middle of the night with servere stomach cramps and sweats to the point that I was doubled up on the floor for an hour. At the time, I did not realize that it could be connected with Yasmin. I also was not feeling myself emotionally; I was quick to get upset and felt pretty down. Finally, my skin was worse than it had been on Ortho, and I did not lose the weight. The positive was that I had very short and light periods (probably only a day or two).
