01

Schedule your first prenatal visit

Early prenatal check-ups help confirm your pregnancy, estimate your due date, and ensure both you and your baby are progressing well. Once you have a positive pregnancy test, book an appointment with your healthcare provider.

02

Eat a healthy, balanced diet

Your baby's development starts from the very beginning. Eat nutrient-rich foods, stay hydrated, and take folic acid or iron supplements only as recommended by your doctor. Small, balanced meals throughout the day can also help manage nausea and maintain energy.

03

Make safe lifestyle choices

Stay active with doctor-approved activities like walking or prenatal exercise, but avoid alcohol, smoking, hot tubs, and medications that haven't been prescribed during pregnancy. Every healthy choice supports your baby's growth and wellbeing.

How do I use the Pregnancy Due Date Calculator?

A normal pregnancy typically lasts between 37 and 42 weeks. Simply select the first day of your last menstrual period (LMP) and click Calculate Due Date. The calculator will estimate your expected delivery date based on the information provided.

How is my due date calculated?

By default we count 280 days (40 weeks) forward from the first day of your last period, following Naegele's rule. If you estimate by conception, ultrasound or IVF transfer, we adjust the count so the result reflects the dating method you chose. Longer or shorter cycles shift the estimate accordingly.

Why is due date calculation important?

Knowing your estimated due date helps you and your doctor plan prenatal check-ups, screening tests and vaccinations at the right time, and track whether your baby is growing on schedule. It's a guide for the weeks ahead — only about 1 in 20 babies actually arrive on the exact date.

When should I see a doctor?

Book your first appointment as soon as you have a positive pregnancy test. Contact your doctor sooner if you have heavy bleeding, severe abdominal pain, a high fever, or any condition such as thyroid issues or diabetes that may need closer monitoring during pregnancy.
