Could this be spotting?

Sorry for the oddness of the picture. I was in the middle of trying to update my Glow log, so I just sort of checked my CM and saw that it wasn't clear or white, so I grabbed the first thing next to me that would show what color was going on. I'm TTC and never experienced spotting before- 2 live births- but I can't tell if this is the start to my period, either. Usually my period is just there when I wake up and major. But I also just had to get a D&C; from my still birth back in July, so maybe my period is just different now. What do y'all think? I don't want to get my hopes up for nothing. I've taken 4 negative te

sts in a week and a half.
