Implantation or just a very light period?

Alesia

I need help ladies! I had a positive opk test on Tuesday (I tested 4 times that day), but Wednesday morning I woke up with VERY LIGHT spotting, I'm talking SUPER LIGHT PINK...it lasted MAYBE 2-3 hours and it only showed up when I wiped..anywho..fast forward to this morning, again...VERY LIGHT spotting that lasted MAYBE 2 hours....and then nothing. So I'm curious, does this sound like implantation or just a super light period?
