Decreased fetal movement at 37 weeks of pregnancy is usually not a sign of impending labor, but may be due to fetal hypoxia in the uterus, or due to a decrease in amniotic fluid volume, etc. If a woman is about to give birth at 37 weeks of pregnancy, the following signs of impending labor may occur. If a woman is about to give birth at 37 weeks of pregnancy, the following signs of labor will usually appear, first of all, there may be a significant increase in vaginal secretions, which is also called the cervical mucus plug discharge, and at this time there may also be irregular abdominal pain, which is also caused by pseudocontractions, so there will be occasional tightening and hardening of the abdomen, usually more frequent at night, and will naturally decrease during the day. It is usually more frequent at night, and will naturally decrease during the day. Many women may also experience a small amount of vaginal bleeding, also known as erythema, prior to labor and delivery, which is mainly due to detachment of the fetal membranes from the wall of the uterus at the opening of the cervix. Usually about 24 to 48 hours after the onset of these symptoms, regular uterine contractions may occur, which then cause an official onset of labor. If you are 37 weeks pregnant and suddenly experience a significant decrease in fetal movement, it is often important to consider that the abnormal manifestations are due to a decrease in amniotic fluid volume, a decrease in the range of fetal movement, or an umbilical cord factor that causes the fetus to suffer from a lack of oxygen in the uterus. This is why it is important to go to the obstetrics department of the hospital as soon as possible for fetal heartbeat monitoring and, if necessary, biophysical scoring to confirm the exact problem.
