During pregnancy, a series of physiological changes occur in the whole body of the pregnant woman to adapt to the needs of fetal growth and development. If these changes go beyond the physiological range, or if the pregnant woman herself suffers from a chronic disease that cannot adapt to the various changes during pregnancy, then both the pregnant woman and the fetus can develop pathological conditions that can bring certain harm to the mother and child. Therefore, pregnant women need to do regular obstetric examinations to determine the development of the fetus and their own safety, so as to ensure a safe delivery. The first maternity checkup] time: determine the pregnancy If you usually have regular menstruation, after your period, buy a pregnancy test by yourself, if it shows pregnancy, go to the hospital, check HCG, progesterone, estradiol, thyroid function, ultrasound, to determine whether ectopic pregnancy, intrauterine pregnancy is at risk of miscarriage, whether it is a single fetus or a double fetus, whether embryonic development and menopause pregnancy week match. The second maternity checkup] 11-14 weeks of pregnancy The mother-to-be applies for the “maternal health handbook” at the community hospital. The checkup includes measuring blood pressure, weight, feeling the uterus in the abdomen, and hearing the baby’s heartbeat for the first time, which is normally 110-160 beats per minute and may exceed 160. The third maternity checkup: 16-18 weeks of pregnancy In addition to the basic routine checkups to feel the uterine fundus and listen to the fetal heartbeat, blood will be drawn for mid-pregnancy Down’s screening, thalassemia, G-6PD, hepatitis B syphilis AIDS, blood group blood routine, coagulation function, liver and kidney function. Ultrasound will be performed to rule out anencephaly, open spina bifida, single atrium, single ventricle, dwarf, cerebrospinal meninges and other lethal malformations, and to measure the biparietal diameter, head circumference, abdominal circumference, femur length and amniotic fluid volume. This stage can be used for bookkeeping if you have maternity insurance, saving a lot! At this stage, you can start making appointments for amniocentesis to draw amniotic fluid for prenatal diagnosis, mainly to see if there are any chromosomal abnormalities in the fetus. The fourth maternity checkup] time: 22-24 weeks of pregnancy Do fetal malformation screening ultrasound, also known as 4D ultrasound, in addition to measuring fetal growth and development indicators, mainly to see whether there are problems in the development of fetal appearance, whether the fetus has cleft lip and palate, recessive spina bifida, whether the limbs are complete, whether the palms of the hands and feet are present, whether there are no problems with various internal organs, and the development of the fetal brain. The fifth maternity checkup is done at 24-28 weeks of gestation. 75g glucose oral glucose tolerance screening is done, and blood glucose is drawn in fasting, 1 hour and 2 hours after drinking sugar water. If the blood sugar is not well controlled, endocrinologist intervention is needed to give insulin treatment to ensure the safety of mother and child. The sixth maternity checkup] Time: 28-30 weeks of pregnancy The maternity checkup starts every two weeks at this stage. At this stage, you should start to count the fetal movements, and you will be issued a fetal movement count sheet, so you should record every fetal movement. The first thing you need to do is to take a look at the following article: “How to count fetal movements, how to count fetal movements is normal”. The seventh maternity checkup] Time: 30-32 weeks of pregnancy Every maternity checkup physician will ask how the fetal movement is, look at the fetal movement count table, check if there is edema in the lower limbs, see if the weight gain is reasonable, if there is edema or excessive weight gain, you need to do a routine urine test to see if there is proteinuria to be alert to the occurrence of pre-eclampsia, and will explain that you should pay attention to rest, lie on your left side, recheck urine protein regularly, and monitor closely. The patient will be advised to take rest, lie on the left side, have urine protein checked regularly, monitor blood pressure closely, eat a high protein, high vitamin, low fat and low salt diet, and pay attention to calcium supplementation. If the fetus is stunted, intravenous nutritional treatment will be recommended; if the fetus is large, diet control is recommended to avoid the occurrence of giant fetus. The eighth maternity checkup] Time: 32-34 weeks of pregnancy At around 34 weeks of pregnancy, the mother-to-be should have routine blood, urine and leukocyte tests to assess whether there is anemia, proteinuria and vaginitis, and if so, treat accordingly. In case of excessive amniotic fluid or suspected giant fetus, a repeat glucose tolerance test is needed during this period to avoid missed diagnosis of gestational diabetes. The ninth maternity checkup] Time: 35-36 weeks of pregnancy From this stage on, the maternity checkup becomes weekly, and each maternity checkup should be done with fetal monitoring to see the fetal oxygen reserve in the uterus. The tenth maternity checkup] Time: 37 weeks of pregnancy From this stage onwards, you have already entered the full term of pregnancy and may face the problem of delivery at any time. The mother-to-be needs to pay close attention to the situation of pre-labour such as redness, water breaking and abdominal pain. The eleventh maternity checkup] Time: 38 weeks of pregnancy During this period, a fetal ultrasound should be done to assess the fetal weight, amniotic fluid volume, umbilical blood flow sd ratio, and placental maturity. If there is a clear indication for cesarean section, the mother-to-be should prepare for hospitalization. Mothers-to-be who are considering vaginal delivery will have to judge whether they have the opportunity to choose vaginal trial of labor based on the estimated fetal size from this ultrasound. The twelfth maternity checkup] Time: 39 weeks of pregnancy Most pregnant women give birth around 39 weeks, but some of them will continue their pregnancy and need to continue their maternity checkups. However, pregnant women with gestational diabetes whose blood sugar is well controlled need to be hospitalized for planned delivery. The thirteenth checkup: 40 weeks Pregnant women with low-risk pregnancy without complications will have their last checkup and will be admitted to the hospital for planned delivery. Finally, congratulations on having a healthy and lovely baby!
