Standard table of fetal development at each week

During pregnancy, mothers should be most concerned about the growth and development of their babies! Because the unborn baby is very unstable in the mother's abdomen, if we do not pay attention to the growth and development of the fetus, some serious adverse effects may occur immediately. Therefore, it is very necessary for us to pay attention to the growth and development of the fetus during gestational age. This article gives you a detailed introduction to the standard growth chart of the fetus during gestational weeks. Moms who are interested can take a look at it now!

The first thing everyone needs to understand is that it takes about a month for the sperm and egg to combine to form sperm-egg fusion and then for the embryo to implant. Therefore, in the first month, mothers will not feel the existence of the fetus, and the signs of pregnancy are very unclear!

4 weeks: At this time, the combination of sperm and egg has already transformed into an embryo, but has not yet completely transformed into a fetus, which is about 0.2 cm in size. This process will cause changes in the mother's body hormones, and pregnancy reactions will begin to appear!

5 weeks: At this time, the combination of sperm and egg officially turns into a fetus, which means that the pregnancy officially enters the embryonic stage. The fetus has grown to about 0.4 cm. At this time, the small fetal sac can be seen by B-ultrasound, which can determine the health status of the baby!

6 weeks: At this time, the fetus has already developed facial organs, respiratory tract, etc., but they are not fully developed yet, just a rough division, and they need to continue to grow!

7 weeks: The fetus has gradually grown into the outline of a human being. We can roughly see the fetus's limbs, but it is only an outline and the actual appearance cannot be seen clearly!

8 weeks: At this time, the baby's approximate appearance can be seen clearly, and the outlines of the head and limbs can be seen clearly. The early pregnancy is basically over!

In the second half of pregnancy, the fetus has begun to grow. At this time, the fetus's limbs have basically grown completely. We can clearly see some characteristics of the baby. The baby's gender can also be distinguished by some obvious things. The fetus has gradually grown and matured! But one thing mothers need to pay attention to here is that the second trimester of pregnancy is a critical period for the baby's development and formation, and it is very easy to have deformities, so everyone must pay attention to the growth and development of the fetus!

In the late pregnancy, the fetus has basically grown and developed, and the various organs and functions of the body have also fully developed. At this time, the fetus has gradually developed its own consciousness and can interact with mothers. Fetal movement is the best feeling!

The growth and development of the baby is of great concern to us, because the growth and development problems of the fetus reflect the physical and mental health problems of the baby from the negative side, so mothers must pay attention!
