Black-eyed Susan (~40–45 cm) — this week’s plate, drawn at your baby’s scale.
How big is the baby at 31 weeks?
About 41.8 cm (16.5 in), measured head to heel — the size of a black-eyed susan.1
Your baby is active—moving, sucking fingers, and sometimes turning over. Fat continues to fill out the skin, and voices beyond the womb may be becoming familiar.
31 weeks pregnant is how many months?
Week 31 falls in the eighth month of pregnancy. Weeks and months don’t divide evenly, and your antenatal care counts in weeks — so Zohra keeps weeks, and prints the month for the relatives who ask.
That puts you in the third trimester (weeks 28–40).
What might you be noticing?
Practice tightenings. brief, painless Braxton Hicks tightenings may come and go.
Sleep and heat. sleep may be broken, and you may feel warmer.
Digestion. indigestion, bloating, constipation, or piles may remain part of the week.

Let familiar voices fill an ordinary moment if that feels good—reading a grocery list counts. Keep your day flexible around energy rather than forcing energy around the plan.
