A member asked:

What is the common cause of irregulat menstruation? i am regular but i don't have my menstruation period for four months now

A doctor has provided 1 answer

Maybe pregnancy: Take a pregnancy test and that will answer your question. It may not be anything but.... Sometimes women can respond this way to stress or weight changes as well. If there is any large increase in physical activity this could also affect your cycle.
