If you have menstruation before giving birth to a baby, you are mainly in the state of preterm labor, and it is recommended that you send the pregnant woman to the hospital in time to wait for the birth of the baby. Pre-eclampsia is usually characterized by irregular contractions, a feeling of the fetus descending, and redness 24-48 hours before delivery, but the bleeding is small. Menstruation can also be characterized by painful uterine contractions, a feeling of falling discomfort in the lower abdomen or lumbosacral area, and vaginal bleeding, hence the feeling of having a pre-birth period like a period. It should be noted that if the amount of vaginal bleeding is heavy, reaching or even exceeding the usual amount of menstruation, it may be a symptom of placenta praevia, placenta previa, which may affect the delivery of the fetus, or even the life of the pregnant woman and the fetus, which is a more serious situation and needs to be sent to the hospital immediately.
