38w3d with uterus tightening

i have not experienced (to my knowledge lol) any sort of braxton hicks and i’ve had no real signs of labor as of lately, aside from maybe a little more discharge than i’ve been experiencing and lots more peeing lol. i would say tuesday afternoon was the first time i noticed this. just some mild period like cramping with some tightening of my uterus happening. are these braxton hicks or start of real deal? it’s happening again right now periodically as i’m just laying around. i can definitely tell it’s getting tight/stiff bc after a little it feels normal and soft like a normal stomach lol. ftm so not sure what to look for. i have a scheduled csection bc baby is breeched so i’m trying to be aware so i can get to hospital asap!! :)
