Week-by-Week Developments During Pregnancy

One of the most frequently discussed topics among expectant mothers is the developments that occur during pregnancy. This is especially true for women expecting their first child, as they are particularly curious to track the progress of their pregnancy week by week. In this article, we will examine the developmental stages of the baby in the womb week by week.

1. First Trimester

This period extends from the 1st to the 13th week of pregnancy. During the first trimester, pregnancy is confirmed after the 5th week. It is essential to obtain ultrasound images during this period to monitor for any potential issues. Additionally, at this stage, the baby is very small, and its heartbeat may not be audible in the first few weeks. Therefore, there is no need to worry.

2. Second Trimester

This period covers the 14th to the 27th week of pregnancy. During these weeks, symptoms such as nausea, fatigue, and loss of appetite may frequently occur in expectant mothers. However, this should not be a cause for concern. It is recommended that expectant mothers drink plenty of water and pay attention to their diet. The baby's heartbeat becomes distinctly audible during the second trimester. By the end of this period, the baby reaches almost the size of a corn cob. More frequent tests and examinations are conducted at this stage. Expectant mothers also begin to feel the baby’s movements more often. The baby’s hands and face become more defined, making ultrasound images clearer. Additionally, increased fatigue, a greater need for sleep, and an increased appetite are common in expectant mothers. It is crucial for them to pay close attention to their diet by consuming more red meat, white meat, and phosphorus-rich foods.

3. Third Trimester

This period extends from the 28th to the 41st week. The expectant mother’s belly becomes noticeably larger. The baby's bones and internal organs develop rapidly during this period. The baby begins to respond to the mother’s voice and external sounds. Its movements become visible from the outside. A medical examination is conducted in the 32nd week to measure the baby’s size and weight, and the method of delivery (natural birth or cesarean section) is determined.

Starting from the 32nd week, medical check-ups should take place at least once a week. During this period, expectant mothers may experience increased groin and back pain. Heartburn is also common among pregnant women, but this should not be a cause for concern. The baby positions itself head-down in preparation for birth. Weight gain tends to be more pronounced at this stage of pregnancy compared to previous weeks, leading to more noticeable swelling and edema in the body. Therefore, it is advised to reduce the consumption of salt and salty foods. Walking is recommended to facilitate childbirth. Additionally, preparations for the baby’s arrival should begin at this stage.
