Generally, when a primiparous woman reaches the late stage of pregnancy, the baby will be in the pelvis within 2 weeks before delivery, and this time range is mostly 35-39 weeks. The pelvis may occur in a transitional woman while in labor, while a few pregnant women may not be able to be in the pelvis due to various reasons and need to seek medical help to solve the problem in time, such as cesarean delivery. Pregnant women can judge whether the baby is in the pelvis or not according to the week of pregnancy and the symptoms after pelvic delivery. Or during the process of pelvic delivery, some pregnant women may feel increased appetite and smooth breathing due to the baby’s descent, which reduces the pressure on organs such as the stomach and lungs in the upper abdomen. However, due to the baby’s descent, the pressure on the organs and tissues of the lower abdomen is increased, and there will be a feeling of lower abdominal cramping and frequent urination, and they may also feel soreness and discomfort in the pelvis and pubic symphysis, and the number of irregular contractions increases. If the pregnant woman is in good health, she can eat some food in moderation to supplement nutrition and relax her abdominal muscles appropriately to reduce the difficulty of pelvic entry of the baby. If the pregnant woman sits for a long time, she can lean forward while sitting, so that her knees are lower than her hips, which will help the baby to enter the pelvis. If you find that your baby is not in the pelvis for a long time in late pregnancy, you can go to the hospital to check the pelvis and the baby’s condition, if the situation is normal, do not worry too much, regular observation can be done, if the baby is not in the pelvis for a long time, accompanied by other abnormalities such as fetal malposition, fetal heart rate decreases, fetal movement decreases, etc., then you need to seek medical attention in time to deal with the situation to avoid serious consequences.
