IMPLANTATION ??

Kealah
Ok my last Period was July 26-29, I generally have very heavy painful menstrual cycles at least the first 2 1/2  days. Then, August 27th I wiped and there was faint blood. I thought my Monthly just came early. Then nothing again that day. Then the 28-29th I had light spotting on and off and now completely gone. I've been TTC for 6 years so my mind can't even think I could be pregnant because it feels impossible but I just need to know what this could be. My period has never done this before. No other signs besides tired, moody and extra hungry and thirsty but I assumed that was my period arriving soon. Please help!
