After 30 weeks of pregnancy, it is recommended that women visit the hospital every 2 weeks for a maternity check-up, and after 36 weeks, it is recommended that they have a check-up every 1 week. If a pregnant woman has high-risk factors, the number of checkups can be increased as appropriate. After 30 weeks of pregnancy, the fetal development speed is accelerated and it is a critical stage of fetal development, so every 2 weeks maternity check can check whether the fetal development index is normal. If the fetal development is delayed, or the fetus is developing too fast, timely intervention can be made. After 36 weeks of pregnancy, the baby may start at any time, so you need to check once a week to keep an eye on the baby’s growth and development and fetal movement.
