Before you use this guide: Pregnancy weeks are counted from the first day of your last period. Sizes are rough averages, and healthy babies vary. This is general information, not an individual medical assessment, so please confirm personal health decisions with your doctor or midwife.

How your baby is growing

Your baby is about the size of a raspberry. Fingers and toes are beginning to separate, the eyelids and ears are taking shape, and the upper lip and nose are forming.

Muscles are developing, and your baby is already making small movements, though you will not feel them for many weeks. The lungs, kidneys and intestines continue to develop.

How you may be feeling

Nausea and tiredness may be strongest around weeks 8 to 10. You may have headaches, feel dizzy when standing quickly, and notice sore breasts with darker nipples. Your clothes may feel tighter because of bloating, even though your womb is still tucked behind the pelvic bone.

Your to-do list for week 8

When to ask for help

Contact your doctor or midwife straight away for heavy bleeding, passing tissue, or severe cramping. Many healthy pregnancies include light spotting, but it is always right to ask.

For heavy bleeding, severe pain, fluid leaking, a severe headache with vision changes, or a baby who is moving less than usual, do not wait for your next appointment. Contact your midwife, doctor or maternity unit straight away. Our guide to pregnancy warning signs has more detail.
