The omens in the week before the birth of a child include irregular contractions, the feeling of a descending fetus, and the sight of red, etc. There are individual differences, and some pregnant women may not have any omens. 1. Irregular contractions: clinically known as false labor, the uterine muscle layer before delivery increased sensitivity, the frequency of inconsistent, short duration, long interval contractions, night aggravation, not accompanied by dilatation of the mouth of the uterus, can be suppressed by sedative drugs. 2. Fetal descent: when the fetal prelude descends and enters the pelvic inlet plane near the time of delivery, the pregnant woman may consciously feel a reduction in the sense of pressure in the upper abdomen and frequent urination. 3. Redness: before labor starts, the fetal membranes near the cervical opening separate from the uterine wall there, and capillary rupture mixes with a small amount of cervical mucus to flow out in the form of pale bloody vaginal secretions. It should be noted that there are individual differences in the prognosis of pregnant women, late pregnancy abnormalities should be timely medical care, so as to avoid delays in the condition leading to adverse consequences.
