There is no safe, reliable way to make a period start on demand
If your period is late, take a pregnancy test if pregnancy is possible
Check for common causes of delay such as stress, illness, travel, weight changes, intense exercise, or hormonal changes
Talk to a healthcare professional if your period is more than a week late or your cycles are often irregular
Use only medications or hormonal treatments prescribed by a clinician
Seek urgent medical care if you have severe pain, heavy bleeding, fainting, or possible pregnancy complications
