Only a few signs of labor?

I am currently 38 weeks and 3 days with my second baby. With my first at this point I had so many signs he was coming soon and he was born at 39 weeks after my water broke. With my daughter now, I don’t have many signs at all besides the fact that she’s really low in my pelvis and I’m 2cm dilated. I haven’t lost my mucus plug or had my bloody show or anything like that.

Have any of you spontaneously went into labor with very few signs? I’m getting stressed out that she’s going to be way overdue at this point so any stories are good to hear. Thank you ladies in advance.
