Was that your normal period? Considering the way you are taking your birth control, it is impossible to say with any certainty.
You need to learn how to use the pill correctly if you are going to use it at all. For now, because Yasmin does pose a high risk of birth defects, you need to stop taking it all together for at least a month, or until you get your next period.
