How It Works

The Pregnancy Calculator estimates key pregnancy dates based on the information you provide. It uses the following guidelines:

• Due Date: Estimated as 40 weeks from the last menstrual period (LMP).
• Last Period Date: Estimated due date is calculated as 40 weeks from this date.
• Conception Date: Estimated due date is calculated as 38 weeks from this date.

Note: These are estimates and actual pregnancy duration may vary. Always consult with your healthcare provider for accurate pregnancy dating.

Pregnancy Timeline

The typical pregnancy lasts about 40 weeks from the first day of your last menstrual period (LMP) to the estimated due date. Here's how the weeks are counted:

• First Trimester: Week 1 to Week 12
• Second Trimester: Week 13 to Week 26
• Third Trimester: Week 27 to Week 40
