About the Pregnancy Calculator

Pregnancy is counted from the first day of your last menstrual period and lasts about 40 weeks. This calculator shows how many weeks and days along you are, your trimester, your estimated due date and how long is left. It is an estimate — your provider's dating scan is the most accurate guide.
