Weeks 1-4: Fertilization and implantation
In the first week after conception, the fertilized egg starts multiplying its cells and travels down the fallopian tube to the uterus. In the second week, the egg implants itself in the uterus lining. In the third and fourth week, the baby’s organs start forming, including the heart, brain, and spinal cord.
Weeks 5-8: Organ formation and growth
The fifth and sixth weeks of pregnancy are crucial in the development of the baby’s organs. The heart starts beating, and the limbs and facial features start taking shape. In the seventh and eighth weeks, the baby’s brain develops rapidly, and the fingers and toes become distinct. The baby’s size also grows from around 0.5 inches to 1.6 inches.
Weeks 9-12: Fetal movement and gender determination
By the ninth week, the baby is now a fetus and starts moving its limbs, although you won’t feel it until later. The baby’s facial features become more refined, and the genitals start forming, which can allow for gender determination through ultrasound. By the twelfth week, the baby’s digestive system is developing, and the baby is around 2.5 inches long.
Weeks 13-16: Bone development and hearing
During the thirteenth week, the baby’s skeleton starts developing, and the bone marrow produces blood cells. The baby’s ears are fully formed by week fourteen, and the baby can hear sounds like your heartbeat and voice. In weeks fifteen and sixteen, the baby’s muscles and coordination improve, and the baby starts growing hair and eyebrows.
Weeks 17-20: Active movements and facial expressions

Weeks 21-24: Brain development and viability
In week twenty-one, the baby’s brain and nervous system continue developing, and the baby’s senses, such as touch and smell, become more refined.

During weeks twenty-nine and thirty, the baby’s growth rate increases, and the baby gains body fat that helps regulate body temperature. The baby’s bones also become stronger, and the baby’s senses, such as hearing and taste, improve. By weeks thirty-one and thirty-two, the baby’s movements become more restricted due to the growing size, but the baby still moves around and responds to external stimuli.
