Signs of labor

I'm 34.5 weeks along with my second baby, and starting yesterday ive been having moderate pressure in my tailbone/ lower back region. Ive also been having the urge to go number 2 a lot this past week as well as random cramping. Could these be signs that labor is coming? I was induced with my first so I didnt really experience labor until I was actually in the hospital. I havent had any bloody show or water leakage so I havent called me doctor, plus I wasnt dialted at all at the last appointment a couple weeks ago. Just thought I'd see if any other moms have experienced this stuff right before actual labor started. Thank you 😊.
