Does my babies gums look like he’s teething?

Delana

I’m a FTM. My little boy will be 3 months old on the 25th. Here for the last week he was been really fussy, drooling, chewing on his hands, and has been spitting up ALOT. Before this week he’s spit up maybe 3-4 times since he’s been born so he doesn’t have reflux that I know of. Here is a picture of his bottom gums, does it look like he is cutting teeth? I honestly don’t know what to look for.
