What Happens at 40 Weeks?

At 40 weeks, you are ready to give birth! 80% of births occur naturally without needing labour induction. However, if you haven’t given birth by the end of week 40, your midwife or doctor will discuss potential options for induction.

 

What Symptoms Will You Have at 40 Weeks?

Symptoms of early labour include strong, short contractions, lower backache, loss of the mucas plug that has been sealing the cervix throughout the pregnancy.

 

If this is your first baby, labour is likely to last between 12-16 hours. When your contractions are occurring every 5-10 minutes and are lasting 45-60 seconds, you should call your midwife. They will tell you what to do. If you haven't’ planned to give birth at home, they will likely tell you to grab your bags and head out the door to the hospital!
