I am posting this a little late seeing that I am 17 weeks (just a little over 4 months) now. But better late then never. Here is a picture of what my belly looks like at 4 months.

Now since you probably can’t really tell the difference between this picture and the previous picture I overlaid them so you can see the difference. The solid belly is at 3 months and the shadowy part is 4 months. There is defiantly some growth there.
