How soon after the onset of redness the labor pains will occur and how long it will take to give birth are different for each person. However, the most common case is that the lower abdominal pains will occur within 24-72 hours after the onset of redness, and the baby will be born. Of course, there are some patients who do not give birth for a month after seeing red, and this is possible. In addition, it is also important to consider what causes the redness. If the redness occurs after late pregnancy when the fetal membranes and the uterine wall are misaligned and the capillaries in the uterine wall rupture, then it is physiological. The amount of redness is very small, and some patients even show bleeding discharge. If there is a lot of redness and bleeding, you should go to the hospital for an examination and have an ultrasound to find out if there is placenta praevia or placenta abruptio. Therefore, it is important to go to the hospital for examination after seeing red, regardless of whether there is stomach pain or not. If the doctor’s examination is only for preterm labor, after the examination, the only way to go is to wait for labor in the hospital.
