With labor contractions, the patient may feel bouts of abdominal pain or a falling sensation, as well as lower back pain. Symptoms of labor contractions are usually regular contractions, small amount of bleeding and water breakage. 1. Regular contractions: they are usually irregular and weak at first, and then gradually become regular. The pain starts at relatively long intervals and lasts for a relatively short time. The pains occur about once every half hour and last for about ten seconds each time. If they are true contractions, they indicate that labor has entered. 2. Small amount of bleeding and amniotic fluid breakage: There is usually a small amount of bleeding or bloody discharge from the vagina. The rupture of the fetal membranes will result in the outflow of amniotic fluid, known as breakthrough water, which is a bit viscous, colorless and similar to urine. Although not very effective in shortening the cervical canal and opening the mouth of the uterus, the fact that the activity of the smooth muscles of the uterus begins to increase means that it is ready for the eventual delivery of the pregnancy. If the patient experiences any of these symptoms, he or she should cooperate with the doctor and successfully complete the labor and delivery, and if the contractions are too frequent, it is important to inform the doctor.
