After 80 years, Xiao Yun was diagnosed with pregnancy soon after her marriage, and the couple was a bit helpless after the joy, only hearing that pregnancy tests should be done and are important, but there is no way to know exactly how to do it. Their concerns are exactly what many of us young mothers and fathers-to-be want to know, so let’s start with early pregnancy. Question 1: When is the right time to check if I am pregnant? A: Generally, people with regular menstrual cycles can be highly suspected of being pregnant after 10 days of menstruation, and it is not too late to take a urine test at this time. It is also unnecessary to take a urine test and do the test too early, because at this time, there may be a weak positive urine test and the result of the ultrasound not seeing the pregnancy sac, which is similar to the diagnosis of ectopic pregnancy, causing unnecessary panic among doctors and pregnant women themselves, and also causing some unnecessary over-examination. Question 2: What should I do once I have a positive urine test? A: A positive urine test means that you are definitely pregnant. The probability of a false positive is not as high as the rate of a false negative, so there is usually no need to doubt. The next step is to do a transabdominal ultrasound examination within 2 months of menopause, the purpose of which is to exclude ectopic pregnancy, because ectopic pregnancy is a life-threatening obstetrical and gynecological disease, and waiting until symptoms appear will delay treatment; the second purpose is to keep a diagnostic basis for confirming the pregnancy week in late pregnancy. Therefore, an ultrasound examination in early pregnancy is very important, and there is no report of ultrasound causing teratology so far, so there is no need to worry. Question 3: When is the most appropriate time to start pregnancy checkup? A: After the pregnancy is confirmed, if you are a resident of the city, you should first register at the street and community health center of your residence and establish a contact file for pregnant women. In addition, if the pregnant woman has existing basic diseases or medical comorbidities, she can also advance the time of prenatal checkups. Question 4: What items should be checked during prenatal checkups? A: Prenatal checkup is a systematic and continuous management of a pregnant woman and should be fixed in the same hospital. The focus of checkups varies in different weeks of pregnancy. The first checkup is the most comprehensive, and you have to fill out the prenatal checkup card. Later, according to the checkup results, the doctor will make an appointment with you for the next checkup, which is usually once a month at the beginning and once a week at the end of pregnancy if there are no special abnormalities. The most important screening items are Down’s syndrome screening before 20 weeks of pregnancy, fetal malformation screening from 20 to 24 weeks of pregnancy, and sugar screening from 24 to 28 weeks of pregnancy. In short, as long as the prenatal examination card is established, the hospital and doctors will systematically manage you, and the information of prenatal examination will be kept in the hospital, so that any abnormalities will be detected in time and early. Question 5: Who are high-risk pregnant women? What are the differences in prenatal checkups for high-risk pregnant women? A: The range of high-risk pregnant women is very wide. Any medical disease or factors affecting delivery before pregnancy and complications during pregnancy can be included in the high-risk category. For example: too old (>35 years old) or too young (<18 years old); short stature (<1.50 meters); high myopia (vision over 800 degrees); history of bad pregnancy and delivery; hypertension, diabetes, heart disease before pregnancy, or complications of hypertension, diabetes, heart disease during pregnancy, etc. After assessment by the prenatal doctor, if you are a high-risk pregnant woman, there will be a prominent mark on your prenatal examination card, and any doctor who handles you will pay extra attention to you, and the number of prenatal examinations will be increased according to the actual situation, and the examination items will also be increased according to the type of condition. Sometimes you may need to be hospitalized for observation due to the progression of your condition.
