Overdue
A pregnancy is considered full term when delivery occurs between 37 and 42 weeks. Your due date is calculated as 40 weeks into your pregnancy. A pregnancy lasting 42 weeks or longer is termed 'post-term'. Fortunately, 95-98% of women give birth before that time.
After 42 weeks, there are more complications
After 42 weeks, the risk of complications increases. The placenta may have reached its maximum lifespan and may function less effectively. This can lead to decreased amniotic fluid, reduced nutrient supply to the baby, and an increased likelihood of fetal distress. Due to these escalating risks, we advise that from 42 weeks onwards, you give birth under the supervision of an obstetrician. The obstetrician will aim to induce labor.
Between 41 and 42 weeks: membrane sweeping
If you are more than 41 weeks pregnant, we will monitor you more frequently. This is to keep a close watch on you and your baby, and also to try to induce labor before 42 weeks using 'membrane sweeping'. During an internal examination, we check if there is any cervical dilation. If dilation is present, we attempt to separate the membranes from the cervix. We do not break the membranes during this procedure. Membrane sweeping releases prostaglandins, a hormone that helps soften the cervix and may trigger contractions.
Regional differences
There is often debate about what is best for a mother and child between 41 and 42 weeks. Some obstetricians believe in inducing labor at 41 weeks, while others advocate for a more conservative approach. Research to date has not provided definitive answers on the best course of action. As a result, different hospitals may manage post-term pregnancies differently, which can be confusing and raise questions. Feel free to discuss these concerns with your midwife!
Hospital bag
Prepare a packed bag with items for the hospital. Even if you plan to give birth at home, it's handy to have it ready in case you unexpectedly need to go to the hospital. See 'I'm in labor' for what you can pack for the hospital.
Tip: Place a note by the bag listing the last items to be packed, such as phone chargers. This way, your partner can quickly gather the final items when the time comes.
