Is this normal?

Hey there! I just wondered if anybody could help me with this.
​Basically, my last period was almost 6 weeks ago. I am having very strange feelings at the moment. Bloated stomach, nausea, headaches, sore breasts, and certain food tastes strange. I did a test last night and it was negative. I am now having brown spotting, and slight pain in the right side of my stomach. Could the test have been wrong? I still haven't had a period?
