Help! What's this? Tmi!

So yesterday I had some slight crampy feelings in my right lower hip. And I noticed spotting. Not sure if it was from working out or not. Yesterday I would have been 6 days away from my period is what glow says. Well today I'm 5 days from period and getting a lot of this! (See photo below)
It's pretty stringy. Could yesterday have been implantation and I'm just testing to early today?
