Pregnancy Calculator Week by Week: Track Your Journey Accurately! πŸ€°πŸ“…

Pregnancy is a magical journey, and knowing your baby's development week by week can be incredibly exciting! A pregnancy calculator helps you estimate your due date, track fetal growth, and plan ahead. In this blog, we'll guide you through the pregnancy week-by-week breakdown and help you understand how your body and baby evolve. πŸŒ±πŸ‘Ά


⭐ What Is a Pregnancy Calculator?

A pregnancy calculator is an online tool that helps expectant mothers estimate their due date based on the first day of their last menstrual period (LMP). Since pregnancy typically lasts 40 weeks (280 days), this calculator provides an estimated week-by-week timeline of fetal development.
