What is NT in 3 months of pregnancy?

As long as you become pregnant, you must do a prenatal check-up. This is very important. Only by doing prenatal check-ups regularly can you know very closely whether the condition of the fetus in your belly is good. If there is a problem, it can be dealt with in time so that it will not become more serious. There are also many items on prenatal check-ups, mainly including weight, blood and urine tests.

Urine test, the results can be obtained immediately, to check whether the urine contains protein and sugar. Urine tests are done every month.

Gynecological examination, palpate the breasts to see if there are any nodules (cysts or fibroids), check the size of the uterus, and the cervical smear. English-speaking countries consider this test useless and disrespectful to pregnant women. But in many countries, most doctors still perform this test to avoid missing cervical cancer.

Weight. The main purpose of measuring weight is to understand the weight gained by pregnant women in order to avoid the fetus being too large or increasing the risk of gestational diabetes. Zhou Hansheng, chief physician of obstetrics and gynecology, said that the weight gained during pregnancy should be differentiated according to the body mass index (BMI) before pregnancy. For people with a BMI between 19.8 and 26, it is recommended to gain 11.5 to 16 kilograms, for people with a BMI between 26 and 29, it is recommended to gain 7 to 11.5 kilograms, for people with a BMI less than 19.8, it is recommended to gain 12.5 to 18 kilograms, and for people with a BMI over 29, the maximum weight gain is 7 kilograms.

Blood pressure during pregnancy may be slightly lower than before pregnancy. Generally speaking, normal blood pressure should be below 120/80 mmHG. If the blood pressure reaches 140/90 mmHG before 20 weeks of pregnancy, it may be suspected to be chronic hypertension. However, if it continues to be higher than 140/90 mmHG after 20 weeks of pregnancy, it may be diagnosed as gestational hypertension.

Gestational hypertension can hinder the entry of blood into the placenta and affect the absorption of nutrients by the fetus. In addition, if it is accompanied by symptoms of proteinuria, it becomes preeclampsia, which can affect fetal growth and development, cause fetal heart rate deceleration, or even fetal death in the womb.

The height of the uterine fundus can roughly estimate whether the fetal size is consistent with the size at the time of prenatal check-up.

Ultrasound. The ultrasound used during general prenatal examinations is 2D ultrasound. Dr. Zhou Hansheng said that whether to perform an ultrasound examination every time depends on the doctor's habits and the equipment in the clinic. The National Health Insurance prenatal examination only pays for the general 2D ultrasound fee once during the third or fourth prenatal examination. If the doctor does not use ultrasound for every prenatal examination due to various factors, pregnant mothers can also ask the doctor.
