8 weeks pregnant
Your baby is about the size of a raspberry
By Emma Whitfield · Pregnancy & Baby Writer
Your baby at 8 weeks
Fingers and toes are forming (still webbed), and the baby is starting to make tiny movements you can't feel yet. All the major organs have begun to develop.
Your body at 8 weeks
Your womb is about the size of a lemon now. Bloating, constipation and tender breasts are common. Some notice their waistband getting snug before any bump shows.
Common symptoms this week
- Bloating and constipation
- Tender breasts and darkening nipples
- Waistbands feeling snug
- Vivid dreams
Symptom lists are typical, never exhaustive — and having none of them is normal too.
Focus this week
You should be assigned a midwife around now — your booking appointment (usually 8–10 weeks) is the big first one, so note your family medical history to discuss.
Week 8 checklist
- Prepare for your booking appointment (usually 8–10 weeks): family medical history, last period date, any medicines
- Ask about local antenatal classes — free NHS ones book up early
