At 12 weeks, the fetus has reached an important milestone in its development. It is now considered a fully formed fetus and is no longer referred to as an embryo. The 12-week mark is significant because it marks the end of the first trimester and the beginning of the second trimester of pregnancy.
During the first 12 weeks, the fetus undergoes rapid and remarkable development. By the time it reaches 12 weeks, it is approximately 3 inches in length and weighs around half an ounce. The organs and body systems have formed and continue to mature during the following weeks and months.
At 12 weeks, the fetus is able to move its limbs and has functioning reflexes, although these movements may not be felt by the mother yet. It has a fully formed face with all the facial features, such as eyes, ears, and nose, becoming more defined. The fingers and toes are also fully formed, and the fetal skin is covered with a soft, thin layer of hair called lanugo.
What to expect at 12 weeks of pregnancy
At 12 weeks of pregnancy, the fetus is in the early stages of development. It is now considered an embryo and has grown significantly since conception, reaching a length of approximately 3 inches.
During this stage, the fetus has already formed most of its organs and body systems. It has a beating heart, functioning kidneys, and a developing digestive system. The limbs are also well-formed, and the fingers and toes can be seen. Facial features, such as the eyes, nose, and lips, are becoming more defined.
Physical Changes
At 12 weeks, many women start to notice changes in their body. The uterus has grown to the size of a grapefruit and may be palpable above the pubic bone. Some women also experience weight gain and an increase in breast size. Hormonal changes can cause various symptoms, including mood swings, fatigue, and morning sickness.
Ultrasound
At 12 weeks, many pregnant women undergo their first ultrasound examination. This non-invasive procedure uses sound waves to create images of the fetus. The ultrasound can provide important information about the development of the baby and can also help determine the due date. During the ultrasound, the fetus may be seen moving and even sucking its thumb.
It is important to note that every pregnancy is unique, and the development of the fetus can vary. Some women may not experience any symptoms or changes at 12 weeks, while others may have different physical and emotional experiences. It is always best to consult with a healthcare provider to ensure a healthy pregnancy and address any concerns.
Development of a 12-week fetus
At 12 weeks, the fetus has completed its transition from an embryo to a fully-formed fetus. During the first 3 weeks of pregnancy, the embryo undergoes rapid development and starts to form the foundations of major organs and body systems.
