When I was pregnant with my first child, I documented my changing belly size by taking a photo each week. I tried to stay in the same position each time with the same lighting and camera position.  These photos show my belly starting at week 5 of my pregnancy and ending at week 39. The photos posted are in increments of 3 weeks until the last photo which is 4 weeks later. The last image is a Gif animation of all the weeks from 5 to 39.
