There is no safe, reliable way to make a period start immediately
If your period is late, take a pregnancy test if pregnancy is possible
Reduce stress and get enough sleep
Eat regular meals and stay hydrated
Do moderate exercise, not extreme workouts
Avoid smoking, drugs, and excessive alcohol
See a healthcare professional if your period is very late, missed for several cycles, or you have severe pain, heavy bleeding, or unusual discharge
Do not use herbs, supplements, or medications to try to force a period without medical advice
