In obstetrics, delivery before 37 weeks of gestation is considered premature. Premature birth is extremely detrimental to the health of the baby because some of the baby’s body organs are not yet well developed. Pregnant women with signs of preterm labor will show certain symptoms, such as regular contractions, vaginal bleeding, pelvic pain, vaginal discharge and other symptoms. The main clinical manifestation of preterm labor is uterine contractions, initially irregular contractions and accompanied by a small amount of vaginal bleeding or bloody discharge, gradually developing into regular contractions, with the cervical canal first subsiding and then dilating. It is necessary to go to the hospital as soon as possible, because this is a sign that the pregnant woman is in labor, and if you go to the hospital too late, it will not only affect the fetus but also endanger the safety of the pregnant woman. Some women with preterm labor also experience violent vomiting, which is related to changes in hormone levels in the body before delivery. After 8 months of pregnancy, the lower abdomen is normally soft, but if the abdomen becomes hard and accompanied by abdominal pain, it is a sign of preterm labor. Some women with symptoms of preterm labor may also feel the most pain in their pelvis. If there is an uncontrollable flow of fluid from the vagina after 7 months of pregnancy, which is often accompanied by pain in the lower abdomen, it is mostly a sign of premature rupture of membranes, and of course, further examination is required, which is also one of the symptoms of preterm labor. If a pregnant woman has the above symptoms then I am very likely that the baby is going to be born early, so you need to go to the hospital in time for examination, and you should not be too nervous.
