How can i get a better understanding of my menstral cycle if i am so irregular?

Predict Menses: Most women want to predict their cycles. When menses are irregular then you are probably not ovulating. Irregular cycles are normal at the beginning and end of reproduction. Simple: track basal body temperatures or ovulation prediction kits. Opk are expensive if cycles are irregular - start with bbt. Google these terms and see your doc for more details. Best wishes.

Start with calendar: A good way to start is to keep a menstrual calendar. Besides the good old fashioned paper calendar, there are many cooler apps on phones, which make it easier to keep track of your menstrual cycle.
