You can know when your period is coming by paying attention to physical and emotional signs that typically occur about one to two weeks before bleeding starts. Common signs include:
- Tender or swollen breasts due to hormone changes
- Feeling bloated from water and salt retention
- Changes in vaginal discharge, often a reduction or drying up before the period
- Acne breakouts or pimples
- Cramps or pain in the lower belly or back
- Mood swings, irritability, tiredness, or anxiety
Tracking these symptoms along with marking your period start and end dates on a calendar can help you predict your cycle more accurately over time. Many people use apps or fertility awareness methods that analyze cycle length and symptoms to forecast their next period
. Additionally, machine learning models and period calculators use past cycle data to predict future periods, which can be helpful especially if your cycle is irregular
. In summary, by observing your body's premenstrual symptoms and keeping a record of your cycle, you can better anticipate when your period will arrive.
