I was on Yasmin last year for three months- I had dark red/black clots, Stabbing pains in my stomach (Really bad to the point of me crying), and the WORST mood swings ever. I had absolutely no sex drive (I was on the pill for a reason right? Yeah, Waste of money!) I stopped purchasing Yas and actually decided to stay off it for my own well being. I will NEVER go through that pain again.
