BH vs Early labor?

Can BH be consistent? Last night around 9:30 I started timing because I’d been feeling a bit period crampy earlier on and then I had a wave of tightening that would start under my ribs go down my belly and then ended with a soreness in my back. Nothing painful and did not increase in intensity so I drank some water and walked around but they were still happening evenly. The first couple were 20 minutes apart then they kept hovering around 9-10 minutes apart for 2 hours never increasing in pain but remaining even in length and interval. 🤷🏻‍♀️ everyone says BH aren’t consistent but also that contractions are painful. Second child but I only had mild contractions with my first overnight and had to have my water broken completely the next morning because I was leaking fluid for 24hrs then she came quick there wasn’t really a pattern/increase in intensity just mild to intense at the end, so I’m not sure if this is the start of early labor 🤔 I’m 37w+4 my daughter came at 38w. I’m having some mild ones today too still no increase in intensity I haven’t had time to time them much yet but so far still seems to be about 10m apart.

Thoughts?
