Week-by-week pregnancy scan photos

Last modified on Tuesday 3 May 2022

Scan photos are so precious during pregnancy – it's wonderful to see your baby growing and ultrasound pictures can be lovely keepsakes. See how your baby is developing in each week of pregnancy with these ultrasound images, from weeks four to 40.

For parents anxious and excited to see their growing baby, getting a glimpse of your little one on an ultrasound scan is an incredibly special thing. The NHS usually offers two ultrasound scans – one at 12 weeks, and one at 20 – to check your baby's health and, if you want, to predict your baby's sex.

But what does your baby look like the rest of the time? At eight weeks, your growing fetus is still the size of a bean, while at 30 weeks the NHS says that it's grown to the size of a cabbage. Find out what other characteristics your baby is developing each week with these week-by-week pregnancy scans ...
