How do you know labor will begin soon in late pregnancy other than….?

Bloody show, regular contractions, ruptured membranes, "nesting" behavior, I know all that, but what are some subtle, less obvious signs.
I am 37 weeks and 2 days, second child, induced with first (so I don't know what it feels like for labor to start) I have been having a lot more Braxton-Hicks contractions, and more soreness and pressure in my lower abdomen, and the baby's movement has increased. I don't know how to tell if the baby has dropped because he has been low the whole time. Are any of these signs?
