Question about taking belly pics

So this may be a dumb question, but I figured I'd ask:
When you're taking your belly pics (at least at first), are you sucking in/tightening your belly?  I am slim but definitely didn't have defined abs or anything, but with the bloat I am definitely not looking newly (4w6d) pregnant. I figured when I took my pics at least at first that I would flex my stomach a bit because at least then the extra flab isn't getting mistaken for baby belly - what do you all think?
