Labor Signs?

So, I have an appt at my OB tomorrow, but I thought I’d ask y’all for an opinion.

All day long I’ve felt very.. Off.

I slept waaaay longer than usual.

And when I woke up I wasn’t feeling well, I’ve felt very nauseated and have had some lose stools (tmi, my bad).

Kinda felt like I had an upset tummy all day.

Definite achy-ness in lower back, but pretty consistent not really waves.

Kinda felt period like crampness all day long, but nothing I could really time.

And I’ve also felt very anxious, for absolutely no reason?

Sound like labor approaching?
