I've just started taking Yasmin on February 27th 2006. My periods...

I've just started taking Yasmin on February 27th 2006. My periods are always normal as far as how long I have them. Usually about 4-5 days MAX. Yasmin was really great for my cramping. I noticed I didnt have any to be honest. But It is now March 9th and I am still heavily on my period. That is 11 days now and it doesn't look like it's getting any lighter. I know it has to be a result of the pill because I have NEVER had this with any other birth control, or even off birth control. I've read alot of people saying they had lighter periods, but has this happened to any others? It is really worrying me. I am also having a horrible time sleeping. I feel tired constantly and I am tossing and turning all through the night. More so I would like to know about the longer periods and if it is normal.
