Bloating right before bump?

Ann Marie • 35, Boston area. I have a 2-year-old son, pregnant with my second, due July 2018
More of a rant - I've been so bloated the past few days (10w5d today), I *almost* thought I was getting my bump. But no. My below-belly-button area is just starting to firm up, it's the rest of my belly that won't cooperate :). I had to give a presentation at work today and brought out the Spanx to avoid suspicion bc I haven't announced yet.
