26 weeks tummy feels very full

I’m 26w2d and my tummy feels very full, heavy and uncomfortable. It’s been over 4 hours since I last ate so I know it’s probably not from that. It’s almost like my whole tummy just feels tight but even then that’s not the right word to describe the feeling.... it doesn’t hurt it’s just not pleasant.

I’m not even really sure how to describe it other than it feels like I ate a bowling ball made of lead.

I’m sure this is normal but just wanted to double check
