Belly tightness

Pa

I’m 25 weeks pregnant and everyday this week after work, I get home and my stomach feels really tight and it feels higher up. It doesn’t feel like a cramp, it just feels uncomfortable and stretched if that makes sense. I normally lay down for a little while and it goes away. I’m going to tell my doctor my next appointment but it’s the a few weeks away. If it continues, I’m going to just give them a call. Does anyone have an idea what this is?
