A two-month-old baby has already taken its first human form. Two months generally refers to the fetus at 8~9 weeks of pregnancy. At this stage, the fetus grows and develops faster, and it has already taken the shape of a human being, which can be seen through ultrasound. The organs of the fetus are just beginning to develop. Ultrasound can see the fetal heartbeat, can look at the size of the fetal sac and measure the CRL, through which the development of the fetus can be monitored. In the second trimester of pregnancy, pregnant women should pay attention to regular obstetric examination to monitor the growth of the fetus, pay attention to a balanced diet, pay attention to ensure energy intake, prohibit smoking and alcohol, take more rest, avoid strenuous exercise, and if there is any discomfort, consult a doctor in a timely manner.
