It's completely natural to ask: "When will I give birth?" Especially as your due date approaches, the waiting can feel long, and it can be difficult to plan your daily life. The most important thing to know is that the due date is a qualified estimate – not a precise date. Pregnancy length can vary from person to person, and even for the same person, two pregnancies can end at different times.
In Denmark, the due date is typically calculated from the first day of your last menstrual period and is often adjusted after an early ultrasound scan. Many people give birth in the weeks around their due date, but it's common to give birth both before and after. Therefore, it brings the most peace of mind to think in terms of a "birth window" rather than a single specific day.
Below, you'll find practical guidance on what influences the timing, what signs to look out for, and when you should contact the maternity ward.
Due Date and Due Date Calculator - How Your Due Date is Calculated
The due date is the date when the pregnancy is expected to be approximately 40 weeks (around 280 days) from the first day of your last menstrual period. An early ultrasound scan is often used to adjust the due date because it can provide a more precise estimate of pregnancy length than the menstrual date alone.
What can affect when you give birth?
Several factors can play a role, for example:
- Whether you are a first-time mother or have given birth before
- Whether the pregnancy progresses without complications
- Whether there are medical reasons to recommend induction (always agreed with a midwife and doctor)
If you are unsure how your due date was set, ask at your next midwife consultation. Understanding the data behind it can provide peace of mind.
When do you typically give birth? Realistic expectations around weeks 38-41
Many seek a very specific answer to "when will I give birth," but unfortunately, there is no method that can predict it precisely for an individual. A practical rule of thumb is instead to prepare for birth to start in the weeks around your due date.
Think in terms of a birth window rather than a single date
If you plan within a window, it often becomes easier to:
- have transportation and childcare in place
- pack your hospital bag in good time
- discuss with your partner or relatives how you will proceed when contractions start
It's also completely normal to fluctuate between patience and impatience during the last part of pregnancy. Try to make small, concrete plans week by week so that everything doesn't feel "on standby."
Signs of labor - what should you look out for?
Your body can give signs in the days or weeks before labor, but the signs vary, and they don't always come in a fixed order.
Typical signs (without always meaning that labor has started)
- Braxton Hicks contractions, which can come and go
- Pressure downwards, because the baby is further down in the pelvis
- Loss of the mucus plug (can be clear or slightly blood-tinged)
- Water breaking
- Regular contractions that increase in strength and frequency
Always contact the maternity ward if you are unsure, if you have bleeding, if your water breaks, or if the baby's movements change significantly.
When should I call the delivery ward?
It can feel daunting to call "too early," but you are welcome to contact the maternity ward when in doubt.
Situations where it is typically relevant to contact the maternity ward
- If your water breaks, even if you don't have contractions yet
- With regular, increasing contractions
- With heavy bleeding or severe pain you cannot explain
- If you are concerned about the baby's movements
- If you have a fever or feel unwell in a way that concerns you
Maternity wards can provide individual guidance over the phone and help you assess whether you should come in or if you can safely stay home a little longer.
Induction after due date - what does it mean for "when will I give birth"?
Some pregnancies end with a discussion about induction, especially if the pregnancy goes longer than expected, or if there are conditions in the mother or baby that make it safest not to wait. Induction is always an individual assessment, where you will be informed about the advantages, disadvantages, and options.
How to prepare if induction is suggested
- Write down your questions in advance (e.g., method, duration, and what happens step-by-step)
- Ask for an explanation of why it is recommended in your situation
- Talk to your partner about how you want support and breaks along the way
The goal is for you to feel safe and well-informed in the decision.
As you approach your birth window, it can also be nice to get practical things ready for the time after birth. Many choose a comprehensive solution such as the Postpartum collection, where you can find hygiene and support products for the first period. If you want to make it extra easy, a complete package like the New Mum Care Pack can be a straightforward way to have the basics ready all at once.
