Pregnancy week by week › Week 12

Week 12 of your pregnancy

Your baby is about the size of a plum

About 5.4 cm long. The organs have formed, the heartbeat shows up on a scan and the skeleton is hardening into bone.

You this week

The placenta now feeds the baby and hormones settle a little. Your waist may thicken, and you might feel hungrier.

Tips for this week

  • Go to your first appointment with a midwife
  • Think about telling your employer after 12 weeks
  • Look into antenatal classes

Follow week 12 together

Bump Diary shows this every day, with a photo of your bump, shared with your partner. Free on iPhone.
