What are some early labor signs?

Okay so im 37 weeks pregnant and lately i have been gettin very little sleep, waking up at least twice a night to use the restroom and then not being able to fall back asleep, i have been very achey, and i use the bathroom to clear my bowels pretty frequently. I dont think im nesting but then again my mom says that I am. My feet have been getting more swollen these past few days, and yesterday i woke up very dizzy and continued to have dizzy spells throughout the day with some nausea. Could these be signs that I could go into labor soon?
