If there are no comorbidities, it is generally recommended to keep the fetus until 37 weeks to avoid the occurrence of preterm labor; however, if the fetus is comorbid with other diseases, it can be delivered without keeping the fetus in labor. If the pregnant woman has no comorbidities, frequent contractions at 34 weeks of pregnancy are generally recommended to be hospitalized to use drugs to inhibit contractions for fetal preservation treatment, and the use of glucocorticosteroids to promote the maturation of the fetal lungs, and preservation of the fetus to 37 weeks to ensure fetal maturation, so as to avoid preterm delivery, resulting in a variety of preterm delivery complications occur. If the pregnant woman is combined with a sharp rise in blood pressure, severe cholestasis, heart disease, etc., it is not necessary to carry on the treatment of fetal preservation, and terminate the pregnancy in time. If the contractions are frequent at 34 weeks of pregnancy, you should seek medical attention.
