HI Aila, I was on Yasmin 28 for about three years. It really did work well for me. It controlled cramps and mensturation very well and I wasn't affected too much by mood swings.
Although, I can be a bit of a crab sometimes anyway.
I ended up stoping my use last month because it just was too strong for me according to my doctor. I've lost about 30 pounds over the past 9 several months and my body was reacting poorly to the pill with lots of break through bleeding and such.
It is a great pill though.
