4 days late need advice

Im four days late took test last night it was negative. Checked cervix this morning and it was high, and feels soft but im mo expert on this. But when i pulled my finger out it has brown kind of clumpy blood. Nothing is on TP when i wipe and im wearing a liner to see and nothing. I feel sick today and have a headache just tired and out of it. My last period was Nov 3 and i am very regular. Had anyone else had this and turned put pregnant?
