“Women who track their menstrual cycle will find it helpful to know their normal,” says Juliet Owen-Nuttall. “ Stress, the food we eat and our lifestyle all affect our menstrual health so it’s really important that women monitor their cycle to notice sudden changes.”
Knowing this information can help you plan ahead for your next period and be aware of any changes. It is important to remember, however, that no method of tracking your menstrual cycle is 100% accurate. Your cycle may change due to various reasons such as stress, diet, sleep, illnesses etc. This is why fertility tracking is often not an effective form of contraception, as your cycle can vary and it’s hard to tell exactly when you’re ovulating.
