At 8 weeks pregnant, your baby is about 1.6 cm / 0.6 in long and weighs around 1 g / 0.04 oz — comparable in size to a raspberry. Tiny but already taking shape, with all major organs forming.

Week 8 milestones

  • Heart beats around 150 bpm and is visible on ultrasound
  • Tiny fingers and toes are starting to form (still webbed)
  • Eyelids are forming and the brain is rapidly developing
  • Embryo officially graduates to 'fetus' status next week

Tip for week 8

First trimester fatigue and morning sickness often peak around now. Rest when you can, and remember it usually eases by week 12-14.
