Light pink spotting?

Yesterday I was about 5/6 dpo and when I wiped midnafternoon when I went to washroom and there was light pink.. Stringy sticky mess as I will call it (looked like egg whites which I at first found strange)? And then the pink colour was the second thing. 
I wish that I had my phone with me but I as at work.. So nope :( 
Is it possible to implant that early? Or maybe my O day was off from what I thought it was (stopped taking my bbt this month.. Silly me)
