Getting Smaller Each Week?!

S

I posted my bump pic last week noting that I thought my bloat was finally gone and bump had come in, but I guess I was wrong and the bloat is still working its way out? This is my third baby and first properly in my 40s, btw. Check out this progression side by side? From left to right it’s 15w, 18w, and 19w. I feel like I’m getting smaller. Is it just me???
