Can be normal: There can be variations in a woman's menstrual cycle that are considered normal and not to alarm about. If these changes become consistent and constant, then evaluation with a provider can shed some light on a problem. If sexually active, one should always consider a chance of pregnancy even while on the pill. There can always be problems with effectiveness.
