How to Use This Calculator
Using our baby pregnancy calculator is simple. Just follow these steps:
- Enter your last menstrual period (LMP) date or your estimated due date (EDD).

The calculator will display your estimated due date, weeks pregnant, and other key pregnancy milestones. You can also use the chart to visualize your pregnancy progress.
Understanding Your Pregnancy Timeline
Pregnancy is typically divided into three trimesters, each with distinct developments:
| Trimester | Duration | Key Developments |
|---|---|---|
| First Trimester | Weeks 1-12 | Implantation, organ formation, rapid growth |
| Second Trimester | Weeks 13-27 | Baby's movements, visible features, rapid growth |
| Third Trimester | Weeks 28-40 | Full-term development, preparation for birth |
Each trimester brings unique changes and milestones. Our calculator helps you track these developments throughout your pregnancy.
How Due Date is Calculated
The due date is typically calculated by adding 280 days (40 weeks) to the first day of your last menstrual period (LMP). This gives you an estimated delivery date (EDD).
For example, if your LMP was January 1, 2023, your EDD would be October 31, 2023.
Note: The due date is an estimate. Actual delivery dates can vary by several days or weeks.
Calculating Weeks Pregnant
To determine how many weeks you're pregnant, subtract your LMP date from the current date and divide by 7.
For example, if today is May 1, 2023, and your LMP was January 1, 2023, you would be:
Example Calculation
Current Date: May 1, 2023
LMP: January 1, 2023
Days Pregnant: (May 1 - January 1) = 120 days
Weeks Pregnant: 120 / 7 ≈ 17 weeks
