When do you first feel “firm”?

So I am 6w+3d and as I was getting ready for bed before, and I ran my hand around my lower abdominal/upper pelvic region I noticed I felt “firm”. For good measure, I exhaled and let all my bloat hang out and gave a rub again and still felt it just it wasn’t as pronounced as when I was “sucking it in” so-to-speak. It’s my first pregnancy and honestly I think it’s too early to feel anything, but I know everyone is different.

So .. human baby? Food baby? When did you first notice this hard feeling in your belly? Love to hear your thoughts!
