Implantation after preseed

okayyy, soooo I am 8 dpo today! Yesterday I woke up with a headache and was experiencing very mild backaches and period-like cramps off and on, and now today I am also experiencing very mild period like cramps off and on. Well I tried pressed for the first time all through my fertile window. My period is not due for another week. Anyways, me and hubby just bd and after I went to the bathroom and there was blood on the paper not much at all and now its completely gone. I have never experienced this so I am very hopeful that this is implantation bleeding since the timing makes perfect sence....I cant wait to find out....but until then what are you thinking based on all I just told you. (Wont let me post a pic ugh,)
