Medical Checklist
When to see your doctor at week 33
Some symptoms need attention right away. Contact your doctor or go to the nearest hospital if you notice any of these:
- Heavy bleeding (soaking a pad within an hour)
- Severe or persistent abdominal or pelvic pain
- Fever above 38°C (100.4°F)
- Sudden severe headache, blurred vision or upper-abdominal pain (possible preeclampsia)

Frequently asked questions
Labour vs Braxton-Hicks?
Real contractions get longer, stronger, closer; don’t ease with rest or hydration. Braxton-Hicks ease.
Refresher antenatal class?
Yes — refresh contraction timing, breathing, hospital-bag inventory, emergency contacts.
Car-seat practice?
Install and try fitting it now. Removes day-of stress.
For partners
Install the car seat this week and test the install — takes longer than you think.
