tmi photo, light spotting 7dpo , just once

I'm sorry I couldn't figure out how to add the tmi filter 😐 
TMI PHOTOS BELOW 
Had this first photo last night around 8pm and it was 7dpo and the second photo was today at 8dpo- I'm guessing it's just left over from yesterday since I only had the pink blood that one trip to the restroom. I've never had any midcycle or post-ovulatory spotting or bleeding in all the 17 years I've had a period.  
Thoughts?
