The fetus is always of concern to pregnant women and their families. Every family has infinite expectations for the fetus that is about to come into this world. Many parents can't wait to know what the fetus looks like and how it develops in the womb. Therefore, the development of the fetus in each month is the most concerned issue for expectant parents. First, let us introduce to you how big the fetus is at one month. I hope parents can understand it.

Growth of the 1-month fetus About 7-10 days after fertilization, the fertilized egg implants in the endometrium, absorbs nutrients from the mother, and begins to develop. During the first 8 weeks, it should be called an embryo, not a fetus. The size of the embryo in the late third week of pregnancy is about 0.5-1.0 cm long and weighs less than 1 gram, but its shape can be seen with the naked eye. Externally, the embryo cannot clearly distinguish between the head and body, and has gill arches and a tail, which is no different from the embryonic development of other animals. 2 months. Fetal growth At 7 weeks of pregnancy, the embryo is about 2.5 cm long and weighs about 4 grams. The heart, stomach, intestines, liver and other internal organs and the brain begin to differentiate. Organs such as hands, feet, eyes, mouth and ears have been formed. It can be said that it is getting closer and closer to the human form, but it is still small in size and big in head. The chorion becomes more developed, the placenta is formed, the umbilical cord appears, and the connection between mother and fetus is very close. 3 months. Fetal growth At this point, at the end of this period, the embryo can officially be called a "fetus". The fetus is about 7.5-9 cm long and weighs about 20 grams. The tail has completely disappeared, but the shapes of the eyes, nose, mouth, ears and other organs are clearly visible, and the hands, feet and fingers are also clearly visible, almost exactly the same as those of ordinary people. The internal organs are more developed, the kidneys and genitals have grown, the urethra begins to form and excrete secretions, and the fetus is surrounded by amniotic fluid. 4 Months Fetal Growth At the end of the 15th week, the fetus is about 16 cm long and weighs about 120 grams.

The fetus begins to develop from a tiny fertilized egg in the mother's body, so the fetal development process is a long process. For the mother, it is a happy torment. The growth and development of the fetus in the body is the hope of the family. How big is the fetus in one month? This issue is not important. What is important is to protect the fetus and bring it into this world safely.
