FTM. is this early teething?

Charlie

my daughter has been exceptionally fussy the past few days, especially during feeds. she's also been taking many short naps and waking up crying as if in pain, went from sleeping from sleeping through the night to waking up multiple times. shes not anymore gassy than before and no fever though it's hard to tell bc she radiates heat just like her daddy. shes also chewing on her fists and bottles, rubbing her towels and blankets on her gums and drooling a lot more than before, enough to choke on occasionally. I'm a ftm so no teething experience but when I checked her mouth, it looks like you can see where the teeth will come through. is that normal before teething or does it look like she's starting? her bottom gums dont look this defined. I tried searching more about it but could only find images of teething right as the teeth were erupting. she's 2 months 10 days so I know it's a bit early but it's not uncommon for teething to start earlier than 4 months
