Later at night symptoms and conditions

I started Yasmin on the first day of my period (Wednesday). I continued to take the pill as directed once a day at the same time, however started to experience dioherrea. One week later at night time I began vommitting every 15 minutes and had to see a doctor. I vommitted from 6pm-3am and was sick in the stomach (nausea) for 4 days following this. I ended up in the emergency room on the 10th day because the nausea had not subsided and my period had not yet stopped (11th day). The doctor and gyno put it down to the pill, 'Yasmin'. Just thought everyone should know that there are some horrible side effects to this pill and to be cautious, I was horribly sick for 5 days, unable to attend work and university.
