After pregnant palace neck becomes short symptom?

The uterus is like a large inverted pear. The broad part above is the body of the uterus, while the narrow part near the pedicle of the pear is the cervix. After pregnancy, the cervix becomes shorter, about 2 cm long and soft. After labor, the cervix becomes funnel-shaped due to contractions, then flattens, and finally the cervix is slowly opened. The uterine orifice of some parturients was loose, and the uterine orifice began to expand soon after uterine contraction, especially in multipara.

Uterine contraction is the contractile force of the uterus, which refers to the contraction of the smooth muscle of the uterine body. It is paroxysmal, and the contraction and intermittence alternate repeatedly, which is not controlled by the will of the puerpera. Uterine contraction plays an important role in childbirth. Only through effective uterine contraction can the fetus continuously descend along the birth canal to complete childbirth.

From 28 weeks of gestation, the abdomen will often appear false contractions. If pregnant women stand or sit in the same position for a long time, they will feel the abdomen harden in bursts. This is false contractions, which is a normal phenomenon. As long as the pregnancy test is normal, there are not four to six contractions in an hour; Without severe abdominal pain, abdominal stiffness and abdominal drop, expectant mothers need not panic too much.
