signs of labor or just normal late pregnancy?

I'm a FTM and am 36 Weeks tomorrow. I've had a fairly easy pregnancy so forgive me if this sounds silly. For the past few days I've been totally exhausted like never before in my life! I'm talking Olympic strength to move my arm sometimes lol. Also I've had zero appetite which is weird and have been extreeeemely hormonal 😬. I think I've had a lot of BH but can't always tell because I have a high pain tolerance so the mild cramping I don't always feel but my stomach gets hard a lot. Is any of this signs labor could come soon or just regular late pregnancy symtoms? I feel very miserable just being bed or couch ridden and am getting very ready to meet my girl!
