Pregnant women are prone to contractions when they sleep at night, because at night, with the onset of darkness the secretion of contractile hormones in the pregnant woman’s body increases, especially in late pregnancy when the receptors for contractile hormones become more and more numerous, and through constant uterine contractions, the formation of the lower segment of the uterus can be promoted and the cervix can be softened, which is also a preparation for later delivery. In late pregnancy, physiological contractions are a relatively common occurrence, most of them are more pronounced at night, while nothing is felt during the day. If these contractions do not affect the rest of the pregnant woman and are not very frequent, they usually do not affect the pregnant woman and her baby. However, you must go to the hospital for prenatal checkups in time, once a week, and if the pain is more severe or if there is bleeding or redness, you should always seek medical attention.
