The fetal heart monitoring contractions do not necessarily mean that the baby is about to be born, it depends on the regularity of the contractions to determine whether they are pseudo contractions or labor contractions. 1, irregular contractions: fetal heart monitoring is needed in late pregnancy, occasional contractions, generally irregular contractions, no obvious abdominal pain, belong to the pseudo contractions, this is not a sign of labor; 2, regular contractions: if the contractions have regularity, 5-6 minutes once, each time about 30 seconds, and the interval is gradually shortened, the intensity is gradually strengthened, generally is the labor contractions, suggesting that the labor is about to take place. If the contractions are regular, once every 5-6 minutes for about 30 seconds, and the interval time is gradually shortened, the intensity is gradually strengthened, and the contraction pressure reaches 100 or even 150 mmHg, it is generally a contraction of labor, which indicates that labor is about to begin and the woman should be admitted to hospital in time for delivery. Therefore, the presence of contractions in late pregnancy, especially the occasional contraction, is usually not a sign of labor, and it may take another half month to go into labor. Pregnant women should pay attention to counting fetal movements and regular labor checkups. If the contractions become more frequent and regular, it is a sign of impending labor.
