Just wondering when you felt your belly skin get tight and how that compared to stretch marks appearing...

I'm only 22 weeks with my first and feel like I'm stretched to the max, especially after a meal. Belly skin feels tight all the time, and itchy at bedtime. Lotions don't really help much. I'm just waiting for the stretch marks to explode.

Where is the rest of this baby going to fit?!
Is it normal to feel that way?
