I think it's like most birth control pills -- if it's working for you, it works for you. The one GOOD thing about Yasmin in my book is that you'll know pretty quickly if it's the wrong pill for you. I went on it and I had the worst depression of my life -- I was completely hopeless, would cry all the time, even at work, and was so tired I couldn't sit up straight. Thankfully I had mentally reminded myself when I started it that if I had different troubles, to think first if it could be the pill. I went right back to the doctor and changed to a different one, and my problems went away very quickly.
If it's been working for you, I wouldn't sweat it. There are risks with any BCPs, so if you've found one that works, stick with it. Personally, I think Yasmin is the work of the devil...
