For those whose Littles have their first tooth already......

My girl will be 8 months in two weeks and no teeth yet....BUT we are teething and super close! My question is what was it like for your Littles right before the teeth actually cut? My girl just took a screaming and crying fit....for 2 hours!! I was figuring it was her teeth since they seem to be right there, ready to cut through .....but maybe not (she's on antibiotics too and I was warned about stomach discomfort) but she's never been THAT upset for that long before. She even vomited right after I gave her some Tylenol 😭 
So did your little have major pain or issues ?? When do you think i can expect the most pain? Right when they break through? Right before?  
What was your experience with your Littles first teeth?!
