The fluid question
Last reviewed · 2 min read · 6 sources · Plain-text version
Six days past your due date. Why your provider watches the placenta and the fluid around your baby after the due date, and the question to ask about it.
- Size this week
- about the size of a pumpkin
- Length this week
- around 51.2 cm from head to heel

Six days past your due date, the last day of week 40. Tomorrow is 41 weeks. Today's note is about the reason the checks get closer together: the water your baby lives in, and the placenta that feeds them.
Your baby

Your baby is around 51.2cm long from head to heel, about the size of a pumpkin (NHS). They are surrounded by amniotic fluid, and that fluid is one of the things a biophysical profile looks at, along with movement and breathing (AAP).
MedlinePlus explains why it matters now: past the due date, the amount of amniotic fluid may decrease, which can press on the umbilical cord (MedlinePlus). An overly large baby can also make a vaginal delivery harder (MedlinePlus).
Your body
The placenta has been working for months. Past the due date, MedlinePlus says, it may not work as well as it did (MedlinePlus). You can't feel that from the inside, which is exactly why your team checks.
What you can notice is your waters. For most women, contractions begin within 24 hours after the water breaks (MedlinePlus). If you think it has started, even as a trickle, call; the NHS says induction may be needed to reduce the risk of infection (NHS).

The fluid question
Time: 5 minutes, at your next appointment
Ask whether your fluid has been measured yet, and if so, what it showed.
Ask what result would change the plan, and what would happen next if it did.
Ask what you should do at home if you notice fluid leaking, and which number to call.
Write the answers on the same page as your monitoring notes.
Make it work:"Is that normal for this stage?" is a complete question. You don't need the medical words to ask it.
Watch for
Normal
more discharge in late pregnancy.
Call your provider
now for fluid leaking from the vagina; the CDC lists it as an urgent warning sign (CDC).
Normal
a baby who moves in their own usual pattern.
Call your provider
right away for decreased movement (MedlinePlus).
Normal
getting out of breath on the stairs.
Call 911
for trouble breathing, chest pain, or a fast-beating heart, which the CDC lists among urgent warning signs (CDC).
For you
Sleep may be patchy by now. MedlinePlus's advice for the third trimester is short: rest as needed, and walk or exercise most days (MedlinePlus). A nap is not a sign of giving up on the day.
If you're the partner: take a night shift on the worrying. If she wakes and wonders whether something is leaking or moving less, you're the one who gets up, finds the number, and makes the call with her.
If your baby comes before tomorrow's note, the next page is theirs: your first month, starting with their first day.
