Bloating(never get bloating)

sarah
Left is how my tummy is normally and right is a picture just today I've been having bloating for a few days now, my boyfriend has even noticed it and thinks it's weird because he didn't notice it before when I was on my period. To me it's extreme, and weird. I feel like I should go back to the dr because this isn't normal for me :/ all tests I've taken were negative. Left pic is June 24th and Right pic is today, August 17th.
