Think I may be, worried I'm not...

So myself and my SO are trying for baby #1. I'm due on Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> (joys of joys) but I've been bleeding light the last few days. Feel like I'm being naive, but could this be implantation bleeding or is it just general spotting problems? X
