You cannot safely make your period start immediately
If your period is late, take a home pregnancy test if pregnancy is possible
Contact a healthcare professional if your period is more than 1 week late
See a doctor urgently if you have severe pelvic pain, heavy bleeding, fainting, or fever
Avoid unproven methods or herbal remedies to “bring on” a period
Maintain regular sleep, meals, and stress reduction habits
If you want to change your cycle, ask a clinician about hormonal options
