When does the prenatal check up start and how often do I have it?

Under normal circumstances, about 10 prenatal check-ups are done throughout the pregnancy (1) The first prenatal check-up: 12 weeks of pregnancy, confirm the pregnancy in the uterus, and apply for the "Pregnant Women's Health Handbook". (2) The second prenatal checkup:

At 13-16 weeks of pregnancy, routine examinations and blood draws are used for early screening for Down syndrome. There is an abnormal amniocentesis at 16-20 weeks. (3) The third prenatal examination, 17-20 weeks of pregnancy, detailed ultrasound examination (to see the appearance of the fetus, head circumference, abdominal circumference, to see the length of the thigh bone and to check whether there are congenital abnormalities in the spine).

4) The 4th prenatal examination: 21-24 weeks of pregnancy, gestational diabetes screening, routine examination. (5) The 5th prenatal checkup:

At 25-28 weeks of pregnancy, check for hepatitis B antigen, syphilis serum test, measles, etc., and routine examination. (6) The 6th prenatal examination: 29-32 weeks of pregnancy, fetal growth ultrasound assessment, blood test, routine examination (check whether there is lower limb edema, preeclampsia) (7) The 7th prenatal examination:

At 33-35 weeks of pregnancy, ultrasound, fetal weight assessment, routine examination, determination of delivery mode and time, etc. (8) The 8th prenatal check-up: 36 weeks of pregnancy, monitoring of the fetal status, preparation for childbirth, and routine check-ups.

9) The 9th prenatal check-up: 37 weeks of pregnancy, pay attention to fetal movement and routine check-ups, so as to avoid early birth. (10) The 10th prenatal checkup:

At 38 weeks of pregnancy, the fetal position is fixed, the fetal head is down, and the baby is ready for delivery.

Regular prenatal check-ups can understand the entire pregnancy process and health of pregnant women, and once problems are found, they can be detected early** to ensure the health of the fetus and the pregnant mother. Therefore, pregnant mothers should do a good job of each prenatal check-up regularly and don't be lazy.

When it is determined that you are pregnant, you should go to the hospital as soon as possible and establish a pregnancy health care file (manual or card) The contents of the initial examination are: Consultation: 1. The general situation of the pregnant woman:

Age, gestational (first pregnancy), parity (how many times have you given birth), menarche, menstrual cycle, menstrual flow, last menstrual period, previous menstrual period. 2. Whether you have been exposed to toxic and harmful substances, such as: mercury, lead, benzene 3, whether you have suffered from serious diseases in the past, such as:

Hepatitis, tuberculosis, heart, lung, kidney, brain disease, hypertension, diabetes, etc., whether surgery has been done 4, whether there is a genetic history in the family, a history of twins, and a history of tumors Check: 1. Physical examination of the whole body: blood pressure, pulse, height, weight, heart, lung, liver and spleen and other systems of the whole body 2, **Physical examination 3, routine examination of blood and urine 4, serological examination:

Hepatitis A, B, CV, TORCH (see later), syphilis, HIV test, alpha-fetoprotein. 5. Some people need more examinations, b ultrasound, electrocardiogram, blood sugar test and other special examinations -- chorionic chromosome examination to find genetic diseases (see prenatal diagnosis in the second trimester) In order to diagnose pregnancy as early as possible and carry out pregnancy health care in time, pregnancy examination should start from early pregnancy, that is, within 3 months, and the sooner the better. Throughout pregnancy, the specific timing of pregnancy check-ups is:

Check up once within 12 weeks (3 months) of pregnancy to identify the symptoms of early pregnancy in time and start health care as soon as possible; In the second trimester (13-28 weeks of pregnancy), check once a month, screen high-risk pregnancies in a timely manner, increase the number of examinations as appropriate, and give necessary corrections**; In the third trimester (28-36 weeks of pregnancy), it should be checked every six months to find out various factors that affect normal delivery, pregnancy complications and complications in a timely manner; After 36 weeks of gestation until term pregnancy, weekly check-ups are performed to closely monitor the mother and fetus to better prepare for delivery. However, if the pregnancy process is normal and the distance is inconvenient, the number of examinations can be reduced as appropriate. If there is any abnormal finding, you should go to the hospital for examination at any time.

After pregnancy, it is necessary to do prenatal examination according to the gestational week, and two prenatal examinations can be done in the first three months of pregnancy, one is 50 days of pregnancy, to confirm whether it is an intrauterine pregnancy, whether the embryo is viable, and then NT examination can be done at 11 to 13 weeks of pregnancy. 2 to 3 prenatal check-ups are done in 3 to 6 months of pregnancy, one prenatal check-up is done in 4 months of pregnancy, and systematic color ultrasound deformity examination is required in 6 months of pregnancy. From 7 months to 8 months of pregnancy, a prenatal check-up is done and glucose tolerance screening is required.

After eight months of pregnancy, prenatal check-ups should be done every two weeks. Check your baby's development and whether you have comorbidities.

In fact, the prenatal examination will start to be filed after 3 months. I must have done a lot of check-ups before, and from now on, it seems that I have to go to the prenatal check-up every two weeks. The last month is every week.

I went to the hospital to ask and I started to have a prenatal check-up as soon as I was pregnant, once a month, once a month for 8 months, and once every half a month after that, and I had to report to the hospital every week in the last month.

Hello, generally the first prenatal check-up after 12 weeks of pregnancy, the items are to measure your height, weight, blood pressure, uterine height, abdominal circumference, blood routine, blood type, hepatitis A, B and C antibodies, AIDS antibodies, syphilis antibodies, liver function, urine test, electrocardiogram examination, physical examination of various systems of the body, and check the gestational week, and may also do B ultrasound and listen to the fetal heart rate, regular prenatal check-up is very important.

Before the first prenatal examination, it must be clear that the intrauterine early pregnancy embryo is viable, if the color ultrasound indicates that the intrauterine early pregnancy embryo is viable, it is necessary to go to the prenatal clinic of the hospital for the first prenatal examination.

The first prenatal examination should include determining the gestational age, estimating the expected date of delivery to evaluate the high-risk factors of pregnant women, measuring blood pressure, weight and body mass index, and doing ** examination, some of the worse items include hematuria routine blood group identification, fasting blood glucose, liver and kidney function, hepatitis B surface antigen determination, syphilis serum antibody screening and HIV screening.

When you are pregnant, you should go to the hospital for regular check-ups, or go to the hospital for consultation.

The first obstetric examination items of pregnancy include pelvic measurement, gynecological examination, leucorrhea examination, blood test, urine test, abdominal circumference, uterine fundus height examination, fetal heart rate examination and degree B ultrasound examination, etc., which are used to understand the physical condition of the pregnant woman and the development of the embryo, determine whether the ectopic pregnancy is confirmed, and determine whether it is a single birth, twin or multiple birth.

Note: Some blood test items of the first prenatal examination should be fasting, if the gestational age is small, you need to hold urine when doing abdominal gyrus color ultrasound, and the urine should be taken in the middle of the urine test. In addition, it is best for the husband to accompany the husband for the first prenatal check-up so that he can understand the family genetic history, disease answers, etc.

In general, the first examination time should be 6 to 8 weeks, and then at 20 to 36 weeks of pregnancy, it is every 4 weeks, but there are some hospitals in the middle, for example, after 32 weeks, it may also be checked once every two weeks for pregnant women, and then after 37 weeks of pregnancy, once a week, under normal circumstances, the prenatal examination is 9 to 11 times, and then the number of prenatal examinations should be increased as appropriate for high-risk pregnancies. Each prenatal check-up doctor will ask in detail whether there are any special circumstances in the middle, and then check the uterine height, abdominal circumference, blood pressure, fetal heartbeat, these are routine B-ultrasound items, and then the examination is based on the condition of the gestational week. The doctor will make an appointment with you after this examination, and then make an appointment with you for the next examination, what other tests need to be fasting, and then how long it will take.

Generally, about 10 prenatal examinations are required during pregnancy: 1 time in the first trimester, and intrauterine pregnancy is determined at 6-8 weeks; About 5 times in the second trimester, once a month for 12-28 weeks; About 5 times in the third trimester, every two weeks from 28 weeks to 37 weeks, and once a week after term. However, it may be necessary to make more trips to the hospital to open tests, do tests, and see the results of tests.

In addition, if there are pregnancy complications such as pregnancy hypertension and low-lying placenta, it is necessary to increase the number of prenatal examinations appropriately. Color ultrasound does not affect the baby.

Prenatal check-ups for the whole pregnancy should generally be done about nine to thirteen times, the first check-up should be within three months after menopause, and then every one to two months, at the end of the sixth to seventh month of pregnancy, once a month, after eight months every two weeks, and the last month should be checked once a week. If there is an abnormal situation, it is necessary to follow the doctor's instructions for regular reexamination, and insist on doing a good job in prenatal examination, which is an effective method for the health of women and babies, so women must pay attention to prenatal examination.

The most important role of pregnancy examination is to screen whether the fetus can develop late, and the principle of eugenics, but how often does the pregnant woman need to have a prenatal examination? Today I will summarize it for you. <>

1. Observe the growth of the fetusIn the pregnancy cycle, the mother can clearly feel the growth of the fetus, so pregnancy is a prenatal checkup, so that the mother is more assured of a process. Generally, pregnancy is 10 months, and about 10 prenatal checkups are required, and the first time is to check the symptoms of early pregnancy at 3 months and 12 weeks, and to start physical health care. At this time, the mother can clearly see the development of the child, and the second is the second trimester, which is checked once a month to prevent the harm of the disease to the mother.

In this process, the mother's belly may get bigger and bigger, and it is very inconvenient to move. <>

2. Determine the health of pregnant womenIn the process of prenatal examination, it is not only to check the development of the fetus, but also for the safety of the mother's delivery. It depends more on the health of the pregnant woman's development, or whether her own physical health can keep up with the needs of a mother. Many women do not realize this problem, so they must pay attention to whether their body can give birth to the child completely during the prenatal examination.

Then in the third trimester, it is basically checked once every half a month to see if the child is growing normally, and many people do B ultrasound for different times, generally four times B ultrasound is performed to check the development of the fetus. <>

Third, the pre-production inspection Many people think that there is no need to inspect before giving birth, in fact, such an idea is wrong, before giving birth is also to attach great importance to the process of the baby's growth and development, but also to see the baby's position better, during the production period. This is also to make the mother more smooth during childbirth, and at the same time to check the fetal position. So are some simple observations.

In the first trimester, the prenatal check-up is done about once a month, and after the 28th week, the antenatal check-up is done about half a month, and the fetal heartbeat should be monitored at all times.

Prenatal check-ups need to be done every three months, because they can observe the growth of the child and the status of the pregnant woman.

The prenatal check-up during pregnancy is about 1 to 2 months, and the period of the check-up is different depending on the prenatal check-up items, so you should ask the doctor for the specific situation.

One: Check the ruler time.

1. Within three months (12 weeks), the first examination will be conducted;

2. 13-27 weeks, check every four weeks;

35 weeks, checked every two weeks;

Weekly - Before delivery, check once a week.

2: Check and slow down the inspection project.

1. Do the first pregnancy examination around 12 weeks (three months). 2. 13-16 weeks, Second prenatal check-up: Down syndrome screening -20 weeks, Third prenatal check-up 4, 21-24 weeks, Fourth prenatal check-up Gestational diabetes screening 5, 25-28 weeks, Fifth prenatal check-up Hepatitis B antigen Syphilis serum test 6, 29-32 weeks, Sixth prenatal check-up Lower extremity edema Occurrence of preeclampsia Prevention of preterm birth 7, 33-35 weeks, 7th obstruction closure check-up Ultrasound (B-ultrasound) examination Assessment of fetal weight 8, 36 weeks, Eighth prenatal check-up Preparation for childbirth Reduction of AA times 9, 37 weeks, the ninth prenatal check-up Pay attention to fetal movement 10, 38-42 weeks The tenth prenatal check-up Fital position is fixed and the fetal head is lowered.

Hello, you only need to go to the first source talk about B ultrasound at about eight weeks to confirm that there is a fetal heart rate and exclude ectopic pregnancy, and the other is about 12 weeks to hail and build a card, and the doctor with the examination items of the split body will help you arrange the prenatal examination, some important ones should not be missed, such as Tang sieve, glucose tolerance and color ultrasound of large deformities.

I go for a prenatal check-up once a month, and I need to have a total of four check-ups.

The second prenatal check-up is at the 16th week of pregnancy, and I will go to the Down Screening Syndrome to check for deformities and avoid giving birth to a baby with Down syndrome. If a primiparous woman over 35 years of age or a pregnant woman with high-risk pregnancy factors has amniocentesis done directly.

The third prenatal examination was at the 20th week of pregnancy, the second B-ultrasound, to check the four-dimensional color ultrasound, large deformity.

The fourth prenatal examination is at the 24th week of pregnancy, and I will go to the sugar screen to check for gestational diabetes and abnormal bile secretion in pregnancy.

The fifth prenatal check-up is at the 28th week of pregnancy, to do hepatitis B, syphilis screening, if there is a hepatitis B virus-carrying mother, the fetus should be blocked by the virus**, plus vaccination.

3.When you are 8 or 9 months pregnant:

I go for a prenatal check-up twice a month, for a total of four check-ups.

The sixth prenatal check-up is at the 30th week of pregnancy to check for edema and to check for and avoid some factors that may lead to preterm birth, such as gestational hypertension and other conditions. Electrocardiogram.

The seventh prenatal examination is at the 32nd week of pregnancy, obstetric examination, blood routine, urine routine, and preterm birth factors.

The eighth prenatal examination was at the 34th week of pregnancy, the third ultrasound examination, small deformity. Check if the fetus has an umbilical cord around the neck. Check the growth and development of the fetus, whether it is small, the ninth prenatal examination is the 36th week of pregnancy, the fetal position check to see if the fetal position is correct, if there is a need to correct the relevant measures.

4.In the last month of prenatal life:

I go to the prenatal check-up once a week, and I need to check it up 4 times in total. Fetal heart rate monitoring is performed every time.

The tenth prenatal examination is at the 37th week of pregnancy, the fourth ultrasound, to check the maturity of the placenta and the measurement of pelvic size to see if the head and pelvis are commensurate, so as to determine the mode of delivery.

The eleventh prenatal check-up is at the 38th week of pregnancy, fetal heart rate monitoring, and cervical degree score.

The twelfth prenatal examination is the 5th ultrasound at the 39th week of pregnancy to check the placental maturity and cervical degree score.

The thirteenth prenatal visit is at the 40th week of pregnancy, when the cervix is scored.
