Most of the reasons for a small amount of fluid coming out at 38 weeks of pregnancy are due to increased secretion caused by cervical ripening in late pregnancy or premature rupture of membranes, etc. The cervix will gradually ripen in late pregnancy. The cervix will gradually mature in late pregnancy, at this stage the cervix will become softer and shorter, and the cervical canal will disappear, so it is easy to have an increase in fluid discharge. This usually has no effect on the mother and the fetus. Just pay attention to regular prenatal checkups. Premature rupture of membranes can also lead to a small amount of vaginal fluid discharge in late pregnancy. For example, if the amniotic sac ruptures through a small opening, there will be a small amount of fluid coming out several times. In this case, you should be hospitalized in time to avoid infection in the uterus. If there is a small amount of fluid coming out at 38 weeks of pregnancy, you need to go to the obstetrics department of the hospital, and be given relevant examinations by a professional doctor to check the secretions and make clear whether it is premature rupture of membranes, and if it is premature rupture of membranes, you need to be hospitalized to avoid delaying the condition.
