Please help

I've been TTC for 7 months now. I had what I thought a rly light period 2 weeks ago and I've been having symptoms for a week now. I'm rly nauseous and it's getting worse everyday. I took a test a 4 days ago and it was negative. I also have about 4 other symptoms, but I'm so worried that I'm just willing the symptoms because I want it so much. Anyone have any advice?
