If you are sexually active, you need to rule out pregnancy as a cause.The other causes are: (1) emotional or physical stress or illness(2)inadequate diet(3)abnormal level of thyroid hormone(4)high levels of prolactin hormone which is released in the brain(5)polycystic ovarian syndrome(6)extreme physical activityIf the irregularity continues then you may need to consider visiting your doctor for an assessment which may include blood tests and imaging.I hope this helps
