Spotting today has me worried

An

I’ve had some period-like cramps today, and when I went to the bathroom, saw some light pink spotting on the TP. I’m 14dpo, and I got my first positive test result on Sunday. I’m terrified that this is a chemical pregnancy, and don’t even know where to begin. If there any chance that this is just implantation bleeding?

What signs should I look for, and is this something I should be calling my doctor about?
