Pregnant women may present with a range of clinical symptoms prior to delivery, including uterine contractions, increased urinary frequency, painless vaginal bleeding in small amounts, and ruptured amniotic fluid. The most common symptoms before delivery are uterine contractions and painless vaginal bleeding. Uterine contractions usually change from irregular contractions to regular contractions, each contraction lasts 30 seconds and the interval between contractions is 5-6 minutes, when the uterus is fully opened, the interval between contractions becomes shorter to 1-2 minutes; painless vaginal bleeding means seeing red, if the bleeding is large or abnormal symptoms such as abdominal pain appear, prompt medical consultation should be made. In addition, as the fetal head descends, the pressure on the bladder will lead to more frequent urination, and the rupture of fetal membranes will lead to rupture of amniotic fluid, which is also a sign of labor initiation. When labor starts, you should get enough energy, get out of bed between contractions, and relax to avoid excessive tension.
