Test tomorrow? Or no? A bit of tmi.

So... I was supposed to start yesterday, had a few dots of brown, but no official period. It's strange, like super wet with the tiniest bit of brown in it. Not even enough to fill one tampon over two days. I hadn't planned on testing, figuring period was just around the corner...but it would be so great if I got my bfp on christmas! How likely do you guys think it is that this is implantation bleeding? Do you think i should say screw it and take the test in the morn? Going crazy. :) baby dust to everyone, and happy holidays!
