Faint line, is it possible?

Malory

Ok so, I had a peak digital OPK on Dec 18, so I’m thinking it’s possible that I’m 8 DPO, but I also had some light bleeding on Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> and Christmas then it mostly stopped (still spotting a little). Is it possible for this to be more than an indent? It looks kind of dark to me to be an indent, but I can’t tell if it has color (I’m always bad at that). Any thoughts would be appreciated!
