Pregnancy Week Calculator
Find out exactly how many weeks and days pregnant you are right now.
Overview
A pregnancy week calculator tells you your exact gestational age - how many weeks and days pregnant you currently are. This is essential information for tracking your baby's development and scheduling prenatal care.
Pregnancy is calculated from the first day of your last menstrual period, not from conception. This means you're considered "2 weeks pregnant" at conception.
Knowing your exact week helps you understand what's happening with your baby, what symptoms are normal, and when key milestones and appointments should occur.
