I'm currently 8 weeks with twins. 
Before pregnancy I had a bit of a "ponch" that was squishy but could look like a bump when I was bloated. 
I've lost 5 pounds in the past 4 weeks, probably as a result of not drinking anymore (for the past 5 weeks since finding out) and because my appetite has changed and I can't manage the heartier foods.
That being said, today my belly is starting to feel more firm. The squish is mostly gone. 
Anyone else have similar experiences around 8 weeks?
