Sticky baby dust!

I found out Monday that I'm pregnant with our first baby. I should be about 5w5d today. On Tuesday I had one single spot of light pink blood when I wiped (sorry, TMI). I called my advice nurse who assured me that everything is probably fine. And then I called again today because it just freaked me out. Now I'm scheduled to go in early Wednesday to check on things! I am praying for a happy sticky baby! My test lines have gotten darker since I experienced that tiny bit of blood, but I can't help but worry! Crossing my fingers.
