Every week of pregnancy is a unique chapter in your baby's development. Our calculator gives you a detailed overview, and this article walks you through the key milestones of each gestational week.
Weeks 1 to 4 are the cycle preparation and fertilization phase. In week 5, the neural tube starts forming. By week 9, the embryo becomes a fetus. By week 12, your baby can curl their fingers and toes, and vital organs are fully formed.
At week 16, your baby's eyes can move slowly. At week 20, the genitals are formed, and ultrasound scans can identify the baby's biological sex. By week 24, your baby develops taste buds and starts showing startle reflexes.
By week 28, your baby's eyes can open and close, and they begin to detect light. By week 34, their bones are fully formed but still soft. At week 40, your baby is the size of a pumpkin and ready for birth.

Medical answers to standard queries regarding pregnancy calculations, due dates, and trimester guidelines.
The first 12 weeks (first trimester) are generally considered the most critical, as all of the baby's vital organs are forming and the risk of spontaneous miscarriage is highest.
A baby's heart begins to beat around week 5 to 6 of pregnancy, which can often be seen or heard on an early ultrasound scan.
