Latch problem experiences?

Sydney
Hello ladies! 
I've been EBF my 2.5 mo daughter since she was born. We never had any latch issues. She has always been a pro until yesterday. She started making a squeaking/clicking sound when she eats. I read on kellymom that this is a sign of a bad latch, and that it can be fine and normal or could be a sign of a problem. I don't have any nipple pain and she's having plenty of wet diapers still. 
Has anyone experienced this?
