Full term. Average weight around 3.4kg (7.5lbs) in the UK. The baby is approximately 51cm from head to toe. They are fully developed and ready to meet the world. The heart has beaten approximately 54 million times since it first started. The baby's brain will continue developing rapidly for the first two years of life.
You may feel impatient, anxious, excited, or all three. If your due date passes, try to be patient - this is very common. Your midwife will monitor you closely and discuss options for induction if needed. Continue monitoring baby movements and attend all scheduled appointments. Try to rest, stay hydrated, and do things that help you relax.
Going past 40 weeks is very common. Your midwife will offer increased monitoring and typically discuss induction at 41 weeks per NICE guidance. You will have regular checks to make sure you and your baby are well. Induction is offered at 41 weeks because the risk of stillbirth increases with advancing gestation beyond this point (per 2021 NICE NG207 guidance).
A due date is an estimate. Only about 4% of babies arrive on their exact due date. Most babies are born within two weeks either side. Nuhah's due date calculator provides your estimated date, but your baby will come when they are ready.
Key signs include regular contractions that get stronger and closer together (use Nuhah's contraction timer to track these), your waters breaking, a show (mucus plug), and persistent lower back pain. If you think you are in labour, call your maternity unit for guidance.
Induction typically involves prostaglandin pessaries or gel to soften the cervix, sometimes followed by artificial rupture of membranes and an oxytocin drip. The process can take 24-48 hours. Your midwife will explain each step and you can ask questions at any point.
