11 DPO - cramping! Cramping! Cramping!

Christine

Help me someone out there!

I am 11 DPO and have had on and off cramps since last Tuesday (starting 6DPO) and Friday was by far the worst. LOTS of cramping. Then yesterday I had nothing and then today I was nauseous and had bloating and cramping again. I keep saying I feel pregnant but the test is saying negative. My period is due Friday. Please give me advice I am losing my mind.
