Three days past your due date. From here on, your care team will want to look in on your baby more often. Today's note explains how, so the appointment is a check, not a shock.
Your baby

Your body
Nothing about these tests is done to your body beyond a belt and a scan. In a nonstress test, a belt around your bump monitors your baby's heart rate and movements, and no medications are used (AAP). A biophysical profile combines a nonstress test with an ultrasound that looks at the baby's movement, breathing, and the amniotic fluid, and gives a combined score (AAP). The AAP calls ultrasound a "safe and common test" (AAP).
When: MedlinePlus says that at 41 weeks your provider will typically run both, a nonstress test and a biophysical profile (MedlinePlus). Ask yours when it plans to start, and where.

The monitoring explainer
Time: 10 minutes
On a card, write "Nonstress test" and under it: a belt, the baby's heart rate and movements, no medicine (AAP).
Write "Biophysical profile" and under it: the nonstress test plus an ultrasound of movement, breathing, and fluid, with one combined score (AAP).
Write "When?" and leave a space; ask your provider which tests you'll have, on what day, and how long to plan for.
Put the card in your bag with your notes.
Make it work:Bring something to read and a snack. A trace takes time, and it's easier to sit still when you aren't hungry.
Watch for
Normal
a bit more discharge as your body gets ready.
Call your provider
right away if you're leaking amniotic fluid (MedlinePlus).
Normal
a bloody or brownish discharge, which may mean the cervix is starting to open even if active labor is days away.
Call your provider
right away for vaginal bleeding that is more than light spotting (MedlinePlus).
Normal
puffy ankles at the end of the day.
Call your provider
now for extreme swelling of your hands or face; the CDC lists it as an urgent warning sign (CDC).
For you
Being past the date can feel like a test you're failing. It isn't one. The checks this week are routine for anyone who reaches 41 weeks (MedlinePlus). They are how your team keeps watching while you wait, and a good result is information too: it tells you the waiting is still fine.
If you're the partner: the appointments may get more frequent, and they're easier with two. Ask now who's driving to each one, and whether your work knows you may vanish at short notice.
If your baby arrives before the appointment, that's the plan working too: their notes begin at your first month.
