Teething?

My girl is almost 4 months old. She’s been extremely fussy, a huge amount of drool, gnawing on her hands, rosy cheeks, and will not take a freaking nap. I keep trying to see if she’s teething but I can’t tell. I’m a first time mom, I know it would be really early to teeth, however my sister got her first 2 teeth at 4 months old so I know it’s possible. I snapped this pic. I can’t tell if that’s normal how gums look or if the little bumps are her teeth making the progress of coming through. Please y’all be nice. I’ve seen so many rude comments on here lately and I was hesitant to post in the first place
