Pregnancy checkups are special examinations for women during pregnancy, mainly including height, weight, blood pressure measurements, uterine height and abdominal circumference measurements, internal gynecological examinations, breast examinations, external pelvic measurements, determination of blood type and anemia level, electrocardiogram, syphilis seropositivity, HIV screening, and repeated ultrasound examinations throughout pregnancy because of the need to know whether the fetus is healthy. In the early stages of pregnancy, ultrasound is routinely needed to determine early intrauterine pregnancy and whether the fetal heartbeat is normal. between 11-13+6 weeks of gestation, ultrasound is needed to find out whether the thickness of the nuchal translucency layer is normal. between 14-20 weeks, Down’s syndrome screening is needed to rule out trisomy 21 and trisomy 18. between 22-24 weeks, third level ultrasound is needed, i.e. a major screening for fetal malformations. From 24-28 weeks, a sugar-water test, a screening test for gestational diabetes, is done. After 34 weeks of pregnancy, fetal heart monitoring should be done routinely. Throughout the pregnancy is the ultrasound, which should be repeated several times to understand the growth and development of the fetus, changes in amniotic fluid, and the level of the placenta. This pregnancy checkup is a routine checkup, but if there are any abnormalities, other tests should be done.
