8 month old spit up kinda bad?

my 8 month old daughter just spit up kinda bad about ten minutes ago. it was projectile but it wasn't a whole lot. it was liquidy & had the curdled cream cheese look to it too. she usually does spit up, but not projectile. she actually went about two weeks before this without spitting up at all until a few days ago. like I said it hasn't been this bad though. other than this, she has been acting normal, just a little fussy but I think its because she's tired. should I be worried? what should I do about it? thanks so much! :)
