10 days late

I'm ten days late and have been having backaches, extreme nausea and vomiting, headache, Can't eat my favorite in n out or even smell it, I've been craving the weirdest things, and I pee literally every 20 minutes. BUT I've taken 3 test from the 3st day I was late and the 5th day I was late and they came back negative. I'm so confused. Am I just out?
