The absence of contractions may be a normal phenomenon, or it may be related to pathological factors such as pelvic anomalies and secondary contraction weakness. 1. Normal phenomenon: Some pregnant women, especially those with a history of previous labor, may have a relatively loose cervix and mistakenly think that they are experiencing contractions, but in fact, they may not feel them yet and need to monitor and detect contractions through fetal heart rate monitoring or touching with their hands. 2. Pathological factors (1) Pelvic abnormality: if there is trauma or narrowing of the pregnant woman’s pelvis, the descent of the fetal head during contractions can be obstructed, causing the symptoms of contractions without opening the uterus. (2) secondary uterine contraction weakness: if there is fetal intrauterine anomaly or obvious cephalopelvic disproportion, the fetus into the pelvis is not enough to cause fetal malposition, etc. can be caused by pregnant women to open the finger to see red secondary to the weakness of uterine contraction, no uterine contraction. Therefore, pregnant women with no contractions need to go to the hospital in time, closely monitored, under the guidance of the doctor for delivery to avoid adverse effects.
