Signs before labor?

I know everyone is different and I’m probably just over analyzing everything lol. I’m 37 weeks and past 2 days I have been having

Lots more pressure/sore stomach

Peeing literally every 20-30 minutes

TMI but loose bowels multiple times a day and getting extreme cramps and stomach tightening every time before I have to go.

I can literally feel baby head like turn on my V

My last checkup on Friday I was 2cm 70% effaced and baby was -1 station. I am feeling like maybe something is happening. Lol but who knows!! Anyone else remember having any signs before labor started for them?
