The internal examination for the birth of a baby is done after the delivery, the doctor needs to do an internal examination to understand the condition of the pregnant woman’s cervix, the birth canal, and the descent of the fetal head. Only an internal examination can determine these indicators most accurately. However, as long as the pregnant woman cooperates well, it can be tolerated and will not cause significant discomfort. In addition, if a pregnant woman is still not having a seizure more than a week after her due date, it is also necessary to evaluate the condition of the cervix by doing an internal examination and to choose the appropriate method to induce labor to promote cervical maturation in combination with the fetus and the ultrasound. Therefore, internal examination is a very important test in late pregnancy and will be done more often after the delivery, once in 2-4 hours.
