Pregnancy can be an exciting time, but it can also be a bit overwhelming, especially if you're a first-time mom. One of the things you may be wondering is how to calculate your weeks pregnant.
There are two main ways to do this: by your last menstrual period (LMP) or by your ultrasound due date.

Calculating Weeks Pregnant by LMP
This is the most common way to calculate your weeks pregnant, and it's based on the fact that most pregnancies last about 40 weeks from the first day of your last period.
To calculate your weeks pregnant by LMP, add 280 days (or 40 weeks) to the first day of your last period.
For example, if the first day of your last period was January 1, 2023, your estimated due date would be October 8, 2023. This means that you would be 40 weeks pregnant on October 8, 2023.
Calculating Weeks Pregnant by Ultrasound Due Date
If you have an ultrasound during your pregnancy, your doctor will be able to give you a more accurate due date. This is because ultrasounds can measure the size of your baby and estimate how far along you are in your pregnancy.
To calculate your weeks pregnant by ultrasound due date, start with the date of your ultrasound and add or subtract the number of days that your doctor tells you.
For example, if your ultrasound shows that you are 10 weeks pregnant on January 1, 2023, your estimated due date would be October 15, 2023. This is because a normal pregnancy lasts about 40 weeks from conception.
