Labour and birth
The third stage of labour happens after your baby is born, when your womb contracts and the placenta comes out through your vagina.
There are two ways to manage this stage of labour:
Your midwife will explain both to you while you're still pregnant or during early labour, so you can decide which you would prefer.
There are some situations where physiological management isn't advisable. Your midwife or doctor can explain if this is the case for you.
Active management speeds up the delivery of the placenta and lowers your risk of having heavy bleeding after the birth (postpartum haemorrhage), but increases the chance of you feeling nauseous and vomiting. It can also make afterpains – contraction-like pains after birth – worse.
If the placenta doesn't come away naturally or you begin to bleed heavily, you'll be advised by your midwife or doctor to switch to active management. You can do this at any time during the third stage of labour.
