The fourth week of pregnancy marks a significant milestone in fetal development. At this stage, your baby is rapidly growing, and you may begin to notice early pregnancy symptoms. This article will provide essential insights into the fourth week of pregnancy, including fetal development, body changes, symptoms, precautions, and frequently asked questions.
What Happens in the Fourth Week of Pregnancy?
At four weeks pregnant, the embryo implants into the uterine lining, forming the placenta. This phase is crucial as the baby’s organs and body structures begin to take shape.
Fetal Development at 4 Weeks
The embryo consists of two layers of cells—the epiblast and hypoblast—which will form the baby’s organs.
The amniotic sac and yolk sac start developing to support the baby.
The neural tube, which will later become the brain and spinal cord, begins to form.
The heart and primitive circulatory system start developing.
The baby is about the size of a poppy seed.

Your body undergoes several hormonal and physical changes to support the pregnancy:
An increase in hCG levels confirms pregnancy.
Mild cramping and implantation bleeding may occur.
Breast tenderness and swelling due to rising estrogen and progesterone levels.
