Has anyone’s tummy suddenly stopped feeling tight?

I’m 17w and last week my tummy was getting consistently tighter - then a few days ago overnight it went soft, and the bump is smaller/less obvious.

Has anyone else experienced this?

I understand your tummy will be tighter/softer based on bloating, but this was a really sudden change and hasn’t changed back since. No change in diet.

Also had an increasing number of fluttery movements before, but since then, nothing.

FTM & first pregnancy- Not sure if there’s a ligit reason to be worried 🤷‍♀️
