Fetal Development Milestones in the First Trimester

• Weeks 1–4: After fertilization, the zygote implants itself into the uterine wall. By the end of the fourth week, the embryo’s heart begins to beat, marking the commencement of a new life.
• Weeks 5–8: Major organs such as the brain, heart, and lungs start to form. Limb buds emerge, and facial features begin to take shape. By the eighth week, the embryo transitions into a fetus, signifying the end of the embryonic stage.
• Weeks 9–12: The fetus continues to grow, with the development of fingernails, toenails, and external genitalia. Movements become more coordinated, although they might not yet be perceptible to the mother.
