Is my two month old teething?

My babygirl, has been slobbering, (which she hasn’t done) very irritable, chewing on fingers, crying whenever her passy falls out of her mouth, restless, barley sleeping, and she has only ate 4 times since 8 am and it’s 1 am now. I’m pretty sure she is teething, I have been putting pacifiers in the freezer and then putting them in her mouth and she seems to enjoy it. Has anyone had a teething two month old? Or close to that age? And if so what did u do to relieve them? This is the second day of this now.
