Are you taking the motilium with the Yasmin? Because if you are not, you should be. The bcp's by themselves don't do anything for you. The protocol is usually 10 mg four times a day for the first week and then go up to 20 mg 4 times a day the second week.
I didn't have problems on the Yasmin, but I know some people have to change the time of day they take it.
Good luck!
