Hard spot in stomach?

Ok so I’m going to ask my doctor at my next ob appointment about it but has this happened to anyone else? I woke up this morning and my stomach was really hard in that one spot and felt like a ball. When I was pregnant with my son he use to roll up into a ball like this and It would look and feel just this but I’m only 8 weeks so I know for sure it’s not baby yet. Second picture is when I was 18 weeks with my first son and first is this morning
