Anyone ever went into labor w/o symptoms?

37 weeks 3 days. I currently have no symptoms or laboring, a few cramps here and there but where my thumb is in the pic below is where baby is. She was higher but now my upper belly is all soft squishy and where my thumb is hard and where I feel her movements at. What does it mean she is that low but I have no other symptoms that I see ppl stating they have before they starting contractions or water broke. FTM here
