As an ASHA worker, I want to record the Last Menstrual Period (LMP) date during the registration of eligible couples and track women who have missed their periods, so I can identify possible pregnancies early and take timely action.

Acceptance Criteria:

1. LMP Date Field Addition:

• • Add a new LMP Date field to:
    • Eligible Couple Registration screen.
    • Eligible Tracking screen.
  • Ensure the field is mandatory during registration.
  • Validate that the date entered cannot be in the future.

1. Dashboard Indicator:

• • Add a Missed Periods indicator to the dashboard, displaying the count of women flagged as having missed their periods.
  • Clicking on the indicator should navigate to a detailed line listing.

1. Line Listing Details:

• • The line listing for flagged women should include:
    • Name
    • LMP Date
    • Village
    • Contact Information
    • Status (e.g., Pending Follow-up, Under Review)
  • Enable navigation to the beneficiary's profile from the line listing for follow-up actions.

1. Missed Period Tracking Logic:

• • Determine missed periods based on:
    • LMP Date entered during registration.
    • Predefined menstrual cycle duration (e.g., 28 days, adjustable in the system settings).
  • Flag women where the difference between the current date and LMP exceeds the defined cycle duration without an updated LMP entry.
