Inconsistent cycle symptoms?

Lyddie
Hello all! 
Does anyone else have pre-period symptoms consistently, then all of sudden none at all? 
About 1 1/2- weeks prior to AF, I always have intense sore breasts, food cravings and cramping. But for the last year, I have random months where I have zero symptoms at all! No sore breasts, cravings, etc, then AF begins normally. 
Does anyone else have sporadic differences like this in their cycles? I've never experienced this before now.
