How to Calculate Gestational Age. 1  Find the date of the first day of your last menstrual period on a calendar. 2  Count the number of full weeks that have passed from the date in Step #1 to today's date. For example, if your last menstrual period started on July 1st and today's date is August 1st, the gestational age is 4 weeks.
The number of weeks you are pregnant depends on the date of your last period. You technically ovulate near what would be called week two of pregnancy, but this is how the vast majority of people, your doctor or midwife included, calculate pregnancy length. Your due date is week 40. If you use the date of ovulation, pregnancy is 266 days long on average. To calculate how many weeks you are you can use a calendar. List your due date or the first day of your last period. Count forward for LMP or backwards from your due date to determine which week is when. (Hint: This is the same day of the week every week!) You can write this on your calendar or use a pregnancy weeks calculator.
