Pregnant? Prepare to be amazed.
This fantastic time-lapse video shows you just how amazing the human body really is.
The short clip, 'This is how a woman's organs shift when pregnant', was uploaded to YouTube a while ago, but caught our eye on Twitter thanks to @fascinatingvids.
It shows the incredible work our bodies do from conception through to birth, with organs moving around to accommodate a growing baby and skin stretching out to allow for movement and growth.
The original clip was taken at the Museum of Science and Industry. It gives a glimpse into what's actually going on inside your tummy during those nine months before you meet your baby.
