What's Happening With Your Baby
The skull bones haven't fused yet; they stay mobile to make the passage through the birth canal easier. The immune system is strengthening. The baby is starting to develop a day-night rhythm.
What's Changing For You
Back and pelvic pain may intensify. Insomnia continues. You may get carpal-tunnel-like numbness in your hands.
To Do This Week
For hand numbness, keep your wrist in a neutral position and use a night splint if one is recommended.
Watch your baby's sleep-wake hours; they'll feel familiar after the birth.

Frequently Asked Questions
How many months is 33 weeks pregnant?
Week 33 of pregnancy falls in month 8 and in the third trimester. Pregnancy months don't run in neat four-week blocks, so the week-to-month conversion rarely lands on a whole number — which is why pregnancy is tracked in weeks.
How big is the baby at 33 weeks?
At 33 weeks your baby is roughly the size of a pineapple: around 43.7 cm long and 1918 grams. These are averages; clear variation between babies is normal, and what matters is the growth curve your doctor is tracking.
How long is left at 33 weeks pregnant?
Assuming a 40-week pregnancy, you have around 7 weeks left at week 33. Most births happen between weeks 37 and 42, so a due date is a range rather than a fixed day.
What should I watch out for at 33 weeks?
For hand numbness, keep your wrist in a neutral position and use a night splint if one is recommended. Watch your baby's sleep-wake hours; they'll feel familiar after the birth. Buy your nursing bras and postpartum supplies now.

When To Seek Care Immediately
Whatever week you are in, contact your doctor or the nearest health facility without waiting if you have: vaginal bleeding or fluid loss, severe persistent abdominal pain, a severe headache, blurred vision or flashing lights, sudden swelling of the hands or face, a fever above 38 °C, burning on urination with fever, persistent vomiting, fainting, or — after week 28 — a clear reduction in your baby's movements. In these situations reach real medical care rather than an app or a web search.
