Bleeding occurs every 28 days for the majority of women, but it is common for the menstrual cycle to be either shorter or longer in duration and for bleeding to start anywhere from day 21 to day 40.
Period length may also vary and last for 3–8 days, with an average of 5 days. Bleeding is often heaviest on days 1 and 2 and starts to become lighter thereafter.
Tracking your period can be useful for several reasons. Period tracking can help you to get to know your own body and cycle and observe any symptoms — such as mood swings or headaches — that may occur during a particular phase of your cycle.
Period tracking can help to identify any changes to your menstrual cycle that may be an indicator of potential health issues. Furthermore, using period tracking apps can tell you when you are likely to be most fertile if you are avoiding pregnancy or trying to become pregnant.
