Teething already?!?!

My first baby started teething at 5mo, and my DD is a little over 7 weeks now. I noticed she's been insanely fussy the past two days, along with a lot of drool, so I felt around her mouth and felt the swelling and the small bump I think is a tooth. 😭
Anyone go through teething super early? I already moved to exclusively pumping since she loves to chew.
