what is going on?!

Hey ladies, I am currently 6 days late but negative tests (I took the first response triple check kit yesterday). I spent all night Friday night throwing up every 30 minutes, still nauseated 3 days later. had some light spotting a couple weeks ago and some more light spotting on Saturday. I also have congestion, stuffy nose, and had a metallic taste in my mouth a couple days ago. do you think I could still be pregnant? I am going tomorrow morning for a blood test but I am feeling very discouraged because it's not showing on a urine test yet.
