(((HUGS))) Sorry you are a blubbering mess.
I will tell you this... you are in the window of time where implantation can happen and is often accompanied by light cramping. So this may be a very very good thing!!
I saw some red tinged CM yesterday for the first time ever, I was 7 DPO and I'm having some light cramping today as well. My LP is between 12-14 days. I have had lots of my friends here have that same kind of brown spotting you are talking about before they got their BFP's. I don't know if it's for sure for you or me for that matter, but I'm hopeful and just wanted to let you know you are not alone.
FF took away points from me for my spotting as well, but I'm not worrying about that. Last month I got 99 points and no baby! So, I wouldn't put too much stock in those points.
Try to keep your chin up and KUP if anything changes.
