ovulation?

Brianna • TTC my Rainbow Baby ! Miscarriage 12/26/14 & Ectopic with Left tube removed 5/20/18😇😇
Ive noticed a week or so before AF I usually get the WORST back ache to the point i cant even wipe myself & My Boobs get sooooo sore even the lightest touch hurts like hell .. Is this ovulation or just AF saying its coming?
