If a woman is trying to conceive it could be helpful to predict her fertility window using menstrual cycle tracking. Same with if she were trying NOT to conceive (so-called "natural family planning") Doctors ask you if you have a regular cycle, the only way to know that is to track your cycle. If you're having some sort of issue with your reproductive organs you may track your cycle for a few months to try to better pin down the issue.
