Crying lots

Hello! Its been two nights now that when i put my LO to sleep, within an hour or 2 she would wake up crying and if i put pacifier in her mouth or pick her up and rock her, she would be ok for like 30 seconds and then start crying again. She would also push and arch her back at times while crying. She also has been waking up up multiple times for soothing. She had 2 x 1.5 hour naps, had a bath and went to bed at 8pm. She has no fever..

Any ideas? She has no teeth yet, is this teething?? Or is there a 9 month sleep regression or something?! 😩

Could it be the transition of her sleeping in her crib in her own room instead of bedsharing with us??
