Details: Tracking pregnancy weeks is essential for monitoring fetal development, scheduling prenatal appointments, preparing for delivery, and understanding which developmental milestones to expect.
Tips: Enter your estimated due date (usually provided by your healthcare provider) and the current date. The calculator will determine how many weeks pregnant you are based on the time remaining until your due date.
Q1: How accurate is this calculation?
A: This calculation provides an estimate based on your due date. Actual pregnancy duration can vary, and your healthcare provider's assessment is most accurate.
Q2: What if my due date was calculated from my last menstrual period?
A: This calculator works with any estimated due date, whether calculated from LMP, ultrasound, or other methods.
Q3: Why 40 weeks for full term?
