Week 27 · Second trimester

27 weeks pregnant

Calla lily

36.6 cm (14.4 in)head to heel

At about 36.6 cm from head to heel, your baby is close in length to a Calla lily (~35–40 cm), drawn here in warm tones around one sculptural curve.

This week, inside

The lungs can now make breathing movements, while the organs continue maturing. Fat is filling out folds in the skin as your baby grows.

What you might be noticing

  • A tired week. fatigue may be more noticeable now.
  • A stuffier night. snoring can become more common because nasal passages may be swollen or blocked.
  • Everyday changes. heartburn, leg cramps, backache, and feeling hot are listed among common symptoms.

Small things that help

Protect one quiet pocket of the day, even if it is only ten minutes. Move one nonessential task to another week and save a photo of the place you rested.

For the record
