Teething?

Hey, moms! My princess will be 12 weeks old on Thursday. The last week or so, she's constantly chewing on her fingers. She's also fussy a lot. I try to feed her thinking she may just be hungry, but that's not the issue. (She eats regularly, but I thought she may be having a growth spurt) Could she possibly be teething?
