I hardly ate today but my stomach is more solid and bloated than ever. I showed early with my 2nd baby but I shouldn't be THIS bloated. I've been a bit bloated the last couple of weeks but not like this. And the scale said I gained 5lbs since yesterday. My fiancée weight is constant on the same scale. I wanted to cry!! Has anyone else had this happen? All the sudden a(n extremely bloated) belly at barely 2 months??
