MMM-PregnancyTracker

A MagicMirror² module that tracks pregnancy progress and displays fetus images based on the current week of pregnancy.

Features

• Displays the current week of pregnancy
• Shows fetus development images for each week
• Provides developmental milestones for the current week
• Shows size comparison (e.g., "Your baby is the size of a lemon")
• Displays days remaining until due date
• Calculates dates based on conception date or Last Menstrual Period (LMP)
• Modern, clean design

Installation

1. Navigate to your MagicMirror's modules folder:

cd ~/MagicMirror/modules

2. Clone this repository:

git clone https://github.com/gowthamravichandran/MMM-PregnancyTracker.git

3. Add the module to your config/config.js file:

{
  module: 'MMM-PregnancyTracker',
  position: 'middle_center',
  config: {
    // See configuration options below
    lmpDate: "2025-01-15" // Format: YYYY-MM-DD
  }
}

Configuration Options

Option	Description	Type	Default
conceptionDate	Date of conception (Format: YYYY-MM-DD)	String	null
lmpDate	Date of Last Menstrual Period (Format: YYYY-MM-DD)	String	null
updateInterval	How often to update the display (in milliseconds)	Number	86400000 (1 day)
showDaysRemaining	Whether to show days remaining until due date	Boolean	true
showSizeComparison	Whether to show size comparison	Boolean	true
showDevelopmentalMilestones	Whether to show developmental milestones	Boolean	true
language	Language for text (for future localization support)	String	"en"

Note: You must provide either conceptionDate or lmpDate for the module to work properly.

Adding Custom Fetus Images

The module looks for fetus images in the images directory. Images should be named according to the week of pregnancy they represent (e.g., week1.png, week2.png, etc.).

If a specific week's image is not found, the module will display a placeholder image (placeholder.png).

See the images/README.md file for more information on adding custom images.

Customizing Developmental Milestones and Size Comparisons

The module uses data from the following files:

• data/milestones.json - Contains developmental milestones for each week
• data/size_comparisons.json - Contains size comparisons for each week

You can edit these files to customize the information displayed by the module.

Updating

To update the module to the latest version:

cd ~/MagicMirror/modules/MMM-PregnancyTracker
git pull
