Full body cramping.

Deepti

Could someone please advise me here. I'm 8dpo and my whole body is so soar. Back cramps, stomach and lower abdominal pain, sore breasts and can't even walk for long without my hips hurting. My period is due on the 16th and I always start spotting 3 to 5 days before my full flow. I've never cramped this much before my period. I haven't tested yet as I want to wait if my period gets delayed.
