Teething - ALL 4 molars at the same tome

Am

Okay, so please tell me I’m not crazy. My 13 month old is cutting all 4 molars at the same time. Teething hasn’t been a problem at all. Lately, she’s been a little more fussy, clingy, and she now not eating ... this girl loves food, she doesn’t ever not eat. She also had a runny diaper last night. Could this all be teething related or does it sound like she may be getting a little bug? Still sleeping great and no fever. I’m just getting worried she’s not eating 😔 feeling a little defeated here.
