Pregnant?

I’m currently 4 days late and I’m never late. I’m having nausea, sore breast and itchy and hard nipples, can’t eat anything due to nausea so I’ve lost like 5 pounds, cramping in lower stomach, and having a hard time sleeping since I can’t get comfortable. I took two hpt that came back negative and a blood test came back negative as well. Has anyone had this happen to the and ended up being pregnant?
