Understanding your baby’s development during pregnancy is essential for monitoring their health and preparing for each stage. Our Fetal Development Calculator helps you estimate your baby’s growth milestones, from the first heartbeat to the final weeks before birth.
The Fetal Development Calculator estimates your baby’s developmental stage based on the date of your last menstrual period (LMP) or your due date. By entering these details, you can learn about key growth milestones, including organ formation, weight gain, and sensory development, aligned with each week of pregnancy.
While the calculator provides helpful estimates, consult your healthcare provider for precise information. Ultrasounds and prenatal check-ups offer the most accurate insights.
