Scared to test

I need some advice ladies!! I thought I had my period this month, but it was way lighter and shorter than normal (3 days of light bleeding). I typically have VERY regular cycles (5 days of regular to heavy). It came a day early too which I really didn't think anything of it, but now I have flu like symptoms and of course have googled the crap out of this. They say it is possible to have what you think is your period and still be pregnant. I have a test in the other room, I'm just so scared of getting a BFN. I guess I should just suck it up and take it huh??? What do you guys think??
