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

The eyelids that have been closed since early pregnancy are starting to open, and your baby can blink. Eye colour may change after birth. Your baby can react to bright light shone on your bump.

The lungs are still growing and developing air sacs. Your baby may be more active in the evening and may have hiccups, which feel like small rhythmic jumps.

How you may be feeling

Backache, pelvic pain and tiredness may build as your bump grows. Heartburn and indigestion are common, and you may notice swelling in your feet and hands. It can be harder to get comfortable in bed.

Your to-do list for week 26

When to ask for help

If your blood group is Rhesus (RhD) negative, your care team will usually talk about anti-D injections around 28 weeks, or earlier after any bleeding. Ask about this if nobody has mentioned it.

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.
