This is not uncommon. The most common things to affect the menstrual cycle are pregnancy or stress of any type. Any type of physical or psychological stress can affect when and if an ova (egg) is released. Moreover, it is not uncommon for a longer period to eventually be associated with more menstrual bleeding as there is a longer period of time for the inner lining of the uterus (endometrium) to accumulate.
