The labor pains do not occur immediately after the redness, most of the pregnant women will have stomach pains after 24-48 hours after the redness. If you have had regular checkups in the past and there are no complications during pregnancy, you do not need to be nervous and can continue to wait for the pregnancy. In late pregnancy, when the lower part of the uterus elongates and thins, the cervix shortens, the fetal membranes near the endocervix separate from the uterine wall, and the capillaries rupture, a small amount of hemorrhage occurs, which mixes with the cervical canal mucus and is then discharged. The amount of bleeding at the sight of red is less, if the bleeding is more, there may be a pathological condition, such as placenta praevia, which needs to go to the hospital for examination in time to avoid adverse pregnancy outcome. Due to the different physique of pregnant women, some pregnant women may experience contractions a week after seeing red, so it is recommended that pregnant women count the fetal movement at home, and do ultrasound and fetal heartbeat monitoring at the right time.
