Your body changes throughout your menstrual cycles so monitoring changes such as changes to discharge lets you know when you're about to start your period, everyone has their own unique cues that tell them when their periods are about to start.

Stress can disrupt your hormone levels, potentially leading to a delayed period. If you have been under significant stress and have experienced other symptoms such as changes in appetite, sleep patterns, or mood swings, it is possible that stress is the cause of your delayed period. It's important to consult with a healthcare provider to rule out any other underlying causes.
