Medical Checklist
When to see your doctor at week 21
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

Frequently asked questions
Can baby taste what I eat?
Yes — flavours pass to amniotic fluid and may shape later food preferences.
Stretch marks preventable?
Genetics drive most of it. Moisturisers reduce itching but don’t reliably prevent marks.
Balance affected?
Yes — centre of gravity shifts. Supportive shoes, careful stairs.
For partners
Cook a variety this week — let the baby sample many tastes.
Prepare for your OB visit
- Discussed GDM-test timing?
- Podiatrist for arch / shoe advice?
