It occurs when the baby’s time inside the uterus is over and it is coming out of the uterus vaginally. The uterus starts to contract(he uterus tightens and relaxes at regular intervals, causing the abdomen to feel hard, then soft. which make the cervix thin out (efface) and open as wide as it can (dilate).  Contractions also help in pushing the baby deeper into the pelvis till it comes through the vagina. Normal labor occurs on 3 steps:

First stage

It takes about 8-12 hours in primigravida (First time to deliver) and shorter in multigravidas (Delivered before). It is the part where the cervix dilates to 10 cm full dilation. Don’t push down and do your first stage breathing exercises.

Second stage

It takes about 30-60 minutes. The baby comes out here. It occurs in a well prepared operative theater. It is preferred to perform the breathing exercises in this stage. The doctor might a small incision between the vagina and the anal opening (episiotomy). It is done to enlarge the vaginal opening to facilitate an easy delivery. Not all deliveries need an episiotomy

Third stage

It takes about 10-30 minutes. The placenta comes out in this stage. When the placenta separates a gush of blood and the cord comes out more. Your doctor massages your abdomen and pulls the placenta out then massages again to help the uterus to contract. The doctor will fix the episiotomy at that time.

Fetal follow-up

The fetus should be followed up all the time of labor using sonic aid Doppler to hear the fetal heart beats or CTG to draw the fetal movements against uterine contractions.
