20 weeks pregnant: body, feeding, and care
Halfway by the calendar. The fetus can swallow, produces meconium, and movements are often clearly felt from this point on.
Body and care — week 20
Halfway by the calendar. The fetus can swallow, produces meconium, and movements are often clearly felt from this point on. Development notes on this page are general education summarized from ACOG patient-education material; they describe typical development, not your pregnancy specifically. Anatomy and growth are confirmed by your own provider and ultrasounds.
This week's checklist
- Note one body question — sleep, appetite, movement, comfort — and bring it to your next prenatal visit rather than searching it at 3 AM.
- Keep prenatal appointments on the schedule your provider sets; bring your questions list.
- Anything that worries you — bleeding, pain, reduced movement later in pregnancy — goes to your provider or urgent care first, never to a website.
