Timing contractions

I’m 38w +1d and my little Arthur is an Olympic athlete inside my uterus. I’ve been having contractions on and off since about 36 weeks but nothing consistent. The last few days though he has gotten even more active and it’s always when I also feel like I’m having contractions so it’s really hard to tell when the contractions end and Arthur is just having fun kicking me really hard in the vagina. Anyone else have their baby get more active when it’s time for labor? FYI at my appointment on Friday I was 80% and 2.5cm dilated. This might be TMI but I checked myself in the shower tonight and I could fit all 4 of my fingers in there fairly easily with no discomfort.
