Having a discharge at 39 weeks of pregnancy does not predict how soon you will give birth, but it is possible to go into labor at any time near your due date.
Being 39 weeks pregnant means that the entire pregnancy is coming to an end, during which a pregnant woman may go into labor at any time. The presence of a discharge, especially one with blood in it, is called redness, and may be a sign of preterm labor.
At this time the pregnant woman may also experience contractions, which may feel hard and tight throughout the abdomen. The contractions may be irregular at first, but gradually become more regular and last longer as time goes on. There may also be water breakage, with a large amount of fluid coming out of the vagina and no odor. In the above cases, you need to go to the hospital in time for labor.
Be prepared for labor at 39 weeks of pregnancy, and go to the hospital in time for any abnormalities and a clear diagnosis.
