Frequent contractions at 38 weeks will usually lead to labor within 3 days, but the exact time varies from person to person. 38 weeks is close to the expected date of delivery and there is a possibility of labor. You should pay attention to the frequency of contractions, the degree of abdominal pain, as well as the vaginal redness and fluid flow, maternal reproductive experience, fetal size, birth canal conditions, etc., combined with the above factors to initially determine the time of delivery.1, the frequency of contractions: if frequent contractions, pay attention to the frequency of contractions, if the interval of 4-5min lasts for more than 30s, usually will be in labor within 24h. If the interval between contractions is greater than 5min, the delivery time can be prolonged; 2, the degree of abdominal pain: there are some pregnant women who have frequent contractions, but no abdominal pain, the delivery time is relatively longer, usually in about 3 days. If frequent contractions are accompanied by obvious lower abdominal pain, the labor will be delivered within 24h; 3. Redness and fluid: if accompanied by redness, the labor will be delivered within 1-2 days. If accompanied by vaginal fluid, labor will also occur within 2 days. If there is a long interval between contractions, no redness and vaginal fluid, the delivery time will be appropriately prolonged, and the patient is advised to seek medical attention to do fetal heart rate monitoring to check whether the fetal heart rate is normal; 4, the maternal reproductive experience: if it is a menstruating woman, it will usually be delivered in about 6-8 hours. If it is a primigravida, the delivery time will be prolonged; 5, the size of the fetus: the delivery time and the size of the fetus is also closely related, if the contractions are frequent at 38 weeks and the fetus is small, it will be delivered within 1-2 days. If the fetus is large, the delivery time will be prolonged. It is recommended that pregnant women control the weight of the fetus during pregnancy to avoid excessive weight gain, which may affect the delivery; 6, the conditions of the birth canal: if the pregnant woman is taller and her pelvis is more spacious, after frequent contractions, the delivery time will be faster. Therefore, when there is 38 weeks of frequent contractions need to be prepared to wait for the birth of goods, as soon as possible to go to the hospital to wait for the birth.
