Frequent contractions in the 9th month of pregnancy. It is best to have an ultrasound to see if the fetus is suffering from ischemia and hypoxia in the uterus. In general, frequent fetal movement in the uterus and ischemia and hypoxia will easily lead to frequent contractions. If the symptoms of fetal ischemia and hypoxia are identified, the pregnant woman should be given oxygen in time to improve the symptoms, which can relieve the frequent fetal movement and improve the phenomenon of frequent contractions. During this period, if the contractions are still too frequent after oxygen inhalation, then you should promptly use drugs that inhibit smooth muscle contraction, magnesium sulfate or nifedipine, which have the effect of inhibiting uterine contractions and play a role in preserving the fetus. If the contractions are too frequent, there is a risk that true contractions may form, leading to the possibility of preterm delivery. During this period, pay attention to bed rest and do not exercise strenuously.
