Nervous!

I got a BFP on a first response today! Unfortunately the digital says no. I know that the digitals require more HCG. I am only 14 dpo today. I had spotting Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> but then nothing since! Should I be worried about the spotting? Has anyone experience this?
