Super super faint line and spotting?

Okay so today im 10 dop, took a first response and it showed up a super super super faint line. So faint that my camera wouldnt detect it but you could see it with your eyes. That made me excited but the problem is im spotting. My AF isnt due til nx Monday. The spotting has be worried because ive had it for 3 days, I thought it was going away yesterday but nope still spotting today. Not sure what to think.
