Baby teething, maybe?

Lorena • Had our baby girl! Ophelia Jean Rose came into the world Nov. 28, 2015!
So our baby is always fussy. Thought it was colic, which it could still be. But today I noticed a white dot on her gums and when I thouched it it was hard and raised up. I know babies normally start with the front teeth first, but I can't think of anything else. I asked my aunt and one of my cousins who has older kids and they both think it's a tooth. The thing is, my baby girl is only 8 weeks old. I'm going to call the dr on Monday to see if it's actually a tooth or what. Any other moms have babies that teethed 
early?
