Why Predict Your Period?

Knowing when your period is coming helps you plan your schedule, prepare supplies, time fertility activities, and identify if your period is late. Women with very regular cycles can predict periods 2-3 months ahead with good accuracy using this calculator.

Period Is Late? What To Do

  • 5+ days late → Take a home pregnancy test
  • 7+ days late with negative test → Contact OB-GYN
  • 3+ consecutive missed periods → Seek medical evaluation
