How long will the contractions last after giving birth to the second child?

After giving birth to the second child, what women fear most is the uterine contractions before each delivery. The duration of this contraction is the most difficult time for people, because every time the contraction occurs, women will feel unbearable pain, and may even break out in cold sweats. Especially during the period before delivery, the contractions will last for about two or three minutes, and the intensity of the pain will become greater and greater.

Uterine contractions are regular contractions of the uterus and are the main force of labor. Uterine contractions are an important feature of labor. They are irregular and weak at first, then gradually become regular, increasingly stronger, longer in duration, and shorter in intervals, such as 2-3 minutes at a time, lasting 50-60 seconds.

The last few months of pregnancy are characterized by irregular uterine contractions, especially in the last few weeks. After the fetal movement, just put your hands on your abdomen and you will feel your abdomen hardening from time to time. This type of contraction is irregular, non-cyclical, and painless. It runs through the entire process of delivery; the auxiliary force is the contraction force of the abdominal wall muscles, diaphragm and levator ani muscles, which only appears in the second and third stages of labor and works in coordination with the main force.

1. Physiological

Physiological uterine contractions can occur from 12 to 14 weeks of pregnancy, manifesting as irregular painless contractions. Pregnant women can feel the tightening of the abdomen and the hardening of the uterus from the abdomen. The number of contractions per day is sparse. Later, as the pregnancy progresses, the frequency and intensity of uterine contractions increase, but there is no regularity, and the intensity will not cause the intrauterine pressure to exceed 2KPa, so there is no pain of labor contractions. Under the action of physiological uterine contractions, the lower segment of the uterus is gradually formed, the cervix tends to soften and mature, and gradually transitions to uterine contractions after delivery.

2. Pathological

Pathological uterine contractions are seen in miscarriage or premature birth. Pathological uterine contractions during pregnancy are relatively strong and can cause the intrauterine pressure to exceed 2KPa, so they are all painful contractions. Miscarriage is often accompanied by uterine bleeding, while premature birth is characterized by the regularity and effectiveness of uterine contractions. If not treated in time, the cervix will shorten, the cervix will dilate, and there will be bloody vaginal discharge, and the threatened premature birth will develop into inevitable premature birth.
