After a woman becomes pregnant, the fetus is still in the early stages of pregnancy at around 12 weeks. At this stage, the fetus has not yet developed well. Some expectant mothers may want to know what the normal growth standard for a fetus around 12 weeks is. So, let's learn about the age of the baby at 12 weeks and 6 days of pregnancy together!
Under normal fetal development, the head to hip length of the fetus should be around 5.5cm at 12 weeks of pregnancy, but this is not absolute. Even if there is a certain deviation in the actual situation of the fetus, it is very normal because the mother may vomit during early pregnancy, which can affect the size of the fetus.
Nowadays, every mother will go to the hospital for regular prenatal check ups during pregnancy. Ultrasound is a necessary examination item, which can provide a detailed understanding of the physical condition of the fetus in the abdomen. At 12 weeks and 6 days of pregnancy, the doctor will have a clear display of how old the fetus is, and the doctor will also infer the specific gestational age of the baby based on this data.
If the mother is able to eat excessively during early pregnancy, the fetus's growth will receive rich nutrients and naturally grow larger, possibly exceeding the standard 5.5cm. On the other hand, if the morning sickness reaction is severe and the mother eats less, it will lead to fetal malnutrition, resulting in a fetal length of less than or only 5.5cm at 12 weeks and 6 days of pregnancy.
