Spotting 9 days after period?

Heather
I've been spotting since I woke up this morning. It's light pink/red and not a lot at all. I'm just using a liner. My and my SO have been TTC for about 6 months now. But I had a fairly normal period, and it just ended 9 days ago. I've never had spotting this early, I've had spotting a few days before my period, but nothing like this. Any ideas?
