HELP!!!!!

Syn
My ovulation was a week ago.. And next week I'm due for AF. I've been experiencing some mild cramps on and off the past few days. As well as some other random symptoms (hot flashes, dizziness, fatigue) here and there. Today my back begins hurting and I'm still experiencing cramps in my lower stomach.. Could this mean anything?!! I've never experienced cramping nor back aches (that feel like PMS) until it's actually time for me to come on so this is a bit different.
