After 28 weeks of gestation, the baby is considered viable. Ultrasound cervical canal length measurement is feasible during labor and delivery, in a way that is usually measured via perineum, as well as routine blood pressure, weight, uterine height and abdominal circumference, blood and urine routine, fetal heart rate, and fetal orientation. Fetal movement is more frequent around 28 weeks of pregnancy, even if the fetal position is not correct, there is no need to be nervous because it is likely to change. Urine routine should be performed almost every pregnancy test, and blood routine should be checked frequently depending on whether there is a combination of anemia, ranging from 2 weeks to a month. Because pregnant women are prone to anemia, poor nutrition after anemia is not conducive to the growth and development of the baby, and may also lead to a decline in their own resistance to induce colds or inflammation, as well as white blood cell and platelet counts; urine routine mainly pays attention to whether the ketone body and urine protein positive, to help exclude gestational diabetes and gestational hypertension; uterine height and abdominal circumference to initially determine whether the size of the baby is consistent with the week of pregnancy, can be combined with ultrasound If the child is small, it is recommended to strengthen nutrition, if it is large, you should actively and properly control the diet, otherwise the child is more than eight pounds is a huge baby, the risk of normal delivery is relatively high. If there is usually a tight belly, it may be a physiological contraction, it does not matter. If the frequency increases, it is recommended to perform cervical length measurement to exclude the tendency of preterm delivery. In short, every maternity checkup should be checked, follow the doctor’s advice, eat less sweets, regular outdoor appropriate exercise.
