Implantation or AF?

Shawntae
Ok so my last cycle was from the 18th to the 26th of June, then I had this period of what I THOUGHT was implantation bleeding which lasted from the 7th to the 13th of this month. So I took 3 pregnancy test, once after the spotting stopped and got a bfn, the second after I missed my period but I took it midday and then the third one the following morning and all three were bfn's. NOW I started spotting very very light last night but it's like once I wipe then I don't see it any more and it happened again today but I still haven't had a full Menstrual this month.. could what I experienced in the beginning of July be a light period and this could be implantation? Side bar: Even though we've gotten negative test it hasn't discouraged us from having sex as much as we do. We just decided to stop trying and let it happen when it wants to happen!! Hopefully this is implantation though *fingers crossed*
