Track your pregnancy journey with our Pregnant Calculator Weeks and Days Baby Center. This tool helps you calculate your pregnancy timeline from conception to delivery, showing you how many weeks and days you've been pregnant.

How to Use This Calculator

Using our pregnancy calculator is simple. Just follow these steps:

Enter the date of your last menstrual period (LMP) or the date of conception if you know it.
Select whether you want to track from LMP or from conception.
Click the "Calculate" button to see your pregnancy timeline.

The calculator will display your current pregnancy week and day, estimated due date, and a visual timeline chart.

Understanding Pregnancy Timeline

A typical pregnancy lasts about 40 weeks (280 days) from the first day of your last menstrual period. However, the average length of pregnancy is 266 days (38 weeks) from conception.

Pregnancy Timeline Formula

If tracking from last menstrual period (LMP):

Pregnancy Week = (Current Date - LMP Date) / 7

If tracking from conception:

Pregnancy Week = (Current Date - Conception Date) / 7

Pregnancy is divided into three trimesters:

First trimester: Weeks 1-12
Second trimester: Weeks 13-26
Third trimester: Weeks 27-40
