Spotting!!?? (Tmi pics)

For the last two days I've been getting this light pinky/orange/brown spotting. I had some light spotting earlier in the week and I assumed that it was ovulation bleeding. Currently I'm about 6-7dpo and have been spotting but only notice it when I wipe. I do have that heavy feeling in my uterus like right before your period starts but it's come and go dull pains. Just in your opinion what does it look like...IB, late ovulation or early period??? And af is due next week Friday 12/12.
