Fetal size at 8 weeks of pregnancy

Conceiving a new life is a very magical process. After the sperm and egg combine, a fertilized egg is formed. The fertilized egg will slowly develop into a fetus. The size of the baby is generally different at different stages of pregnancy. When you are 8 weeks pregnant, it is generally the early pregnancy. During this period, the baby is generally very small. However, many people want to know how big a baby is at 8 weeks pregnant.

Fetal size at 8 weeks of pregnancy

8 weeks: The fetus grows to 1.66 cm. The fetal shape is determined, and the head, body and limbs can be distinguished. The head is larger than the trunk. B-ultrasound shows that the gestational sac occupies about 1/2 of the uterine cavity, the fetal shape and fetal movement are clearly visible, and the yolk sac can be seen.

The embryonic bud is the name of a certain period in the development of the fetus. The embryonic bud period is generally called the 3rd week to 14th week of pregnancy. The embryonic bud is actually an early embryo. At 8 weeks of pregnancy, the fetus grows to 1.66 cm and its shape is determined. The head, body and limbs can be distinguished, and the head is larger than the trunk. B-ultrasound shows that the gestational sac occupies about 1/2 of the uterine cavity, the fetal shape and fetal movement are clearly visible, and the yolk sac can be seen. Therefore, the embryo bud at 8 weeks of pregnancy is about 1.66cm long.

If there is no embryo bud in the 8th week of pregnancy, it may be caused by the following factors:

1. Embryonic factors: Abnormalities in the chromosomes of the genetic material carried by sperm and eggs lead to abnormal development of the embryo.

2. External factors: If pregnant women are exposed to harmful substances in the early stages of pregnancy, such as toxic chemicals, inferior decoration materials, radiation or large amounts of electromagnetic radiation, the development of the fetal bud will also be affected.

3. Maternal factors: If pregnant women are infected with rubella, cytomegalovirus, etc. in the early stages of pregnancy, the pathogens will be indirectly transmitted to the fetus, which will cause fetal malformations.

The embryonic stage is a period that the fetus must go through. During the growth of the fetus, the body will inevitably experience symptoms, but there is no need to worry. What is the normal size of the embryo at eight weeks of pregnancy? This is a question that many mothers are concerned about. When the embryo bud is abnormal, the pregnant mother should go to the hospital for examination and treatment in time. If she follows the hospital's instructions, the fetus will gradually recover.
