The Week of the Due Date — Week 40

There's a mark next to this week on the calendar. I can't read that mark; I'm keeping my own time.

What may be happening this week

The estimated due date is only an estimate; only a small share of births happen on exactly that day. Some pregnancies go past this week too, and follow-up is planned together with the doctor.

A note for you

For the mother, every question and every message may feel a little tiring this week; setting boundaries is possible. For the father or partner, fielding the questions and following the doctor's plan together can be a simple kind of support.

The mark on the calendar is an estimate. Let this note stay a short hello too.

Sizes are averages and every baby grows at their own pace. This page is general information, not medical advice.
