If there are no special circumstances, the first pregnancy test is recommended to be performed around 50 days after menopause. It mainly includes general examination, laboratory examination and ultrasound examination, which can clarify the pregnancy status of the pregnant woman and exclude ectopic pregnancy.1. General examination: The first pregnancy test requires measurement of the pregnant woman’s blood pressure, pulse, weight and electrocardiogram. If elevated blood pressure is found to be greater than 140/90mmHg, it is considered that there may be primary hypertension, and it is necessary to assess whether other organs are involved, and in serious cases, the pregnancy needs to be terminated. It should also help to determine whether the pregnant woman is obese. If the body mass index is greater than 30, it is recommended to control the weight reasonably during pregnancy to avoid excessive obesity; 2. Laboratory tests: usually some basic laboratory tests are needed, including blood type, coagulation function, urinary routine, hepatitis virus, AIDS, syphilis, liver function, kidney function, serum ion, fasting blood sugar, etc. The purpose is to check whether the pregnant woman has underlying diseases. If serious abnormalities are found, such as marked reduction in platelets or severe anemia, further laboratory tests and examinations are recommended, and if necessary, the pregnancy needs to be terminated to avoid the risk of these diseases to the pregnant woman’s life. If a pregnant woman has thyroid-related diseases before pregnancy, it is recommended that the thyroid function needs to be tested during the first pregnancy test, and if abnormal thyroid function is found, a thyroid ultrasound is also required. If a pregnant woman has rheumatologic immune related diseases before pregnancy, such as systemic lupus erythematosus, connective tissue disease, etc., the pregnancy test requires rheumatologic immunology related laboratory tests to pay attention to whether the disease is currently active; 3. Ultrasound examination: the first pregnancy test requires examination of pelvic 3D ultrasound to pay attention to whether there is a fetal heart and fetal bud in the uterine cavity. Generally, women with regular menstrual cycles can see the fetal heart. If there is no fetal heart in the uterine cavity, pay attention to whether there are abnormal echogenic masses in the adnexal area and be alert to ectopic pregnancy. If the pregnant woman has heart-related diseases, she also needs to have a cardiac ultrasound and cardiac function to note whether the heart function is able to tolerate the pregnancy. In addition, if there is no special condition in the first pregnancy test, you can wait for 3 months of pregnancy and have another pregnancy test.
