Period owwies?

Teeny • Mom of one, stepmom of one, and expecting our third boy 1/31/16 👶🏼
I've got back pain, tender breasts, and nausea 5 days before my period. For the past 6 months I've had these symptoms only the day before my period but including major cramps. And yes, nausea is a totally normal part of my cycle ? 
​Do any of you get AF symptoms WAY before your periods?!? For someone with a VERY regular cycle, this is quite troubling...
