Pregnancy calculator

Welcome to your pregnancy journey. Whether you have just seen those two life-changing lines on a test or are planning ahead, understanding your timeline is the first step in proactive prenatal care.

Our Pregnancy Due Date & Milestone Calculator is designed to provide you with more than just a single date. By using the date of your last menstrual period (LMP) or your conception date, this tool maps out your entire 40-week journey, helping you coordinate essential health checks and specialist scans.

Why Your Dates Matter

Accurate dating is the foundation of clinical excellence in obstetrics. It ensures that:

  • Screening is timely: Critical tests like NIPT and the First Trimester Anatomy Scan must be performed within specific gestational windows to be accurate.
  • Growth is monitored: We compare your baby’s measurements against established benchmarks for your specific week of pregnancy.
  • Care is personalized: Knowing your exact stage of pregnancy allows your healthcare team to provide the right support at the right moment.

How to Use the Calculator

Simply enter the first day of your last period or your known ovulation date. The calculator will estimate your Estimated Due Date (EDD) and highlight your transition into the second and third trimesters.

Please note: While a calculator is a fantastic starting point, an early dating ultrasound (typically performed between 7 and 10 weeks) remains the most accurate way to confirm your due date and ensure a healthy start for your baby.
