When the fetus is in a shallow pelvic position, the fetal movement will be felt in the upper abdomen, left and right sides of the mother. If the fetus is in normal occipital anterior position, the fetal movement will kick the left upper abdomen or right upper abdomen of the pregnant woman after pelting. In addition to normal occipito-anterior position, there are other abnormal fetal positions. If the fetus is in breech position at the time of delivery, the fetus may kick the lower right or lower left abdomen of the mother after delivery; if the fetus is in transverse position at the time of delivery, the fetus may kick the sides of the abdomen of the mother after delivery. The abnormal fetal position may bring harm, such as breech fetus may lead to umbilical cord prolapse or intrauterine asphyxia or even death; transverse fetus not corrected in time before delivery may lead to umbilical cord prolapse, fetal death in the uterus, or even obstructed labor and uterine rupture and other dangers. Therefore, mothers should have regular maternity checkups so that any abnormal fetal position can be detected and adjusted early to minimize the risk of delivery. In addition, during the process of pelvic delivery, most pregnant women can feel the fetal position gradually dropping, which may be accompanied by slight pain, and after pelvic delivery, they may experience frequent urination, urgent urination, increased appetite and relief of chest tightness, etc. However, it is still necessary for the doctor to determine whether the fetus has been pelved. There are many reasons why the fetus may not be in the pelvis properly, such as cephalopelvic disproportion, oversized fetus, umbilical cord wrapping around the neck, etc., which may cause the fetal head to fail to descend, or placenta praevia, which may lead to premature rupture of the fetal membranes in severe cases, so if you have abdominal pain, fetal movement and other abnormal symptoms in the second trimester, you need to seek medical attention in time.
