TMI!!!!!! (PICTURE)- Is this implantation bleeding!?

Ok so today at work i randomly got really bad cramps and while i got those i noticed i kinda felt something down there so i went to the restroom and i saw this (this wasnt all at once) i didn't realize it was this much until i checked i was just too busy to when i first noticed. But the thing is i was ovulating from 10th-16th these past days and according to glow the 29th which happens to be a week from now is my expected period. My boyfriend and i had sex on the 9, 12, 18. Not to mention ive been having sore breasts for a little over a week now and my bf and even a coworker mentioned to me that my breast look bigger. To me all this makes me think its is what do you guys think???
