OK I'm going to sound crazy, but my belly is definitely smaller than it was last week. It's flabbier and not as round and firm. I still have an obvious bump and I'm big and all, but is this an actual thing? I'm 18 weeks.

I Googled it (of course) and saw a lot of people noticed that as the bloat went down in the second trimester, but did any of you experience this? Because it's honestly making me kinda paranoid, but I know if I call my doctor (I know, I know) I'm going to feel SO stupid.
