5 month old inconsolable crying, teething?

My LO just turned 5 months today! Last night & tonight (currently) she has been inconsolable, all day she’s okay but once it hits nighttime she’s screaming/ infuriated! I’ve never seeing her this way, my baby usually loves her sleep! Always in bed by 7-7:30 pm yesterday she was woke up at 8:30pm being so fussy I couldn’t put her down, it gradually got worse where I couldn’t even tame her. Screaming in my ear she was so tired rubbing her eyes but screaming, I made my bf take us to the ER where they said “she’s fine”

No fever, no ear/ eye infection, no hair around finger/ toes.

We came home, finally at 4am she was out till 9:30am, she was okay today. I put her to sleep normal time 7pm for her to wake up at 8pm screaming crying, & I noticed her rubbing her mouth. Now I’m thinking teething????? I had camilia liquid here so I popped that open but she’s still screaming, please someone help. She does NOT want dad that makes things worse. We have a yoga ball that sudually does the trick but nope.. I cried twice already because I don’t know what to do ….
