There are hormonal options that can shift when your period starts, but they aren't something to take without guidance. They carry real side effects and aren't suitable for everyone, especially if you have migraines, clotting issues, or other hormonal conditions.
Next Steps
Please see a gynaecologist, who can review your health history and suggest the safest option and correct timing for your situation.
Health Tips
Avoid taking any period-delaying or period-inducing tablet on your own, since the wrong choice can affect your cycle for longer than planned.
