What should I pay attention to during the first ultrasound during pregnancy?

B-ultrasound examination after pregnancy is a very common examination method. Generally speaking, this examination can be performed about 7 weeks after fertilization. B-ultrasound examination after pregnancy can determine whether the pregnancy is present, and can also infer the specific time of pregnancy. The approximate due date can be calculated through B-ultrasound examination. This examination method can also observe the specific condition of the embryo. The following will introduce the issues that you should pay attention to during B-ultrasound examination after pregnancy.

Generally speaking, except for symptoms such as pain and bleeding that require ultrasound examination, it is advisable to have 3-4 ultrasound examinations during the entire pregnancy. At 12 weeks of pregnancy, B-ultrasound can be used to determine whether it is a normal pregnancy and the development of the fetal chorionic villi; in the second half of pregnancy, around 20 weeks, B-ultrasound can be done to determine whether the fetus has malformations and abnormal growth and development, as well as the amount of amniotic fluid. If the fetus is found to be abnormal at this time, the pregnancy can be terminated; in the late pregnancy, generally after 32 weeks, B-ultrasound can be done to see the entire development of the fetus, including the head, limbs, cervical spine and the quality of amniotic fluid; if the pregnancy exceeds 40 weeks, another B-ultrasound should be done, and a caesarean section can be performed if necessary.

Around 18 to 20 weeks of pregnancy, the fetal heartbeat can be heard, usually 120 to 160 beats per minute. Less than 120 beats per minute or more than 160 beats per minute usually indicates that the fetus is suffering from fetal hypoxia and needs immediate treatment, otherwise there is a possibility of intrauterine fetal death. Generally, a gynecological B-ultrasound will not take too long, just a few minutes. Pregnancy checkups in the first three months are very important to prepare for pregnancy. Pay more attention to rest and eat more nutritious food.

It should be noted that some female friends may have a relatively short period of amenorrhea, and at this time they blindly worry about the possibility of pregnancy, so they go for an ultrasound examination prematurely. In fact, such an examination is unnecessary, and premature examination cannot confirm whether the pregnancy is present. In addition, it is necessary to do an ultrasound examination in the second trimester to observe the development of the fetus, especially to determine whether there are any congenital malformations.
