Pregnancy Calculator FITNESS & HEALTH 

This is a complete, single-block HTML solution. It includes the CSS for a modern, responsive design and the JavaScript logic to calculate the Estimated Due Date, Current Progress (Weeks/Days), Trimester, and Countdown.

You can save this code as an .html file and open it in any browser.

Key Features of this Tool:

  1. LMP Calculation: Uses the standard medical rule (Naegele's Rule equivalent) by adding 280 days to the last menstrual period.

  2. Real-time Breakdown: Shows exactly how many weeks and days pregnant the user is.

  3. Trimester Tracking: Automatically identifies if the user is in the 1st, 2nd, or 3rd trimester.

  4. Responsive Design: Works perfectly on mobile phones, tablets, and desktops.

  5. Validation: Prevents users from selecting future dates and provides feedback.

  6. Clean UI: Uses a soft "pregnancy-themed" color palette (pink and white) that is easy on the eyes.
