What are the signs of premature birth?

Preterm birth is a birth between the 28th and 37th weeks of pregnancy. It is usually accompanied by redness, increased vaginal discharge, ruptured amniotic fluid, persistent and regular abdominal pain in the lower abdomen, and gradual descent of the fetal head. Because the baby is young, it needs to be kept in an incubator for a period of time after birth to prevent apnea.
