Implantation Bleeding One Sided Pain Implantation Bleeding?

Implantation bleeding? - implantation bleeding one sided pain

Ok, I swore I was never one of those who gave the TMI, but I can not help myself, so here goes. My final time was 21 September ... I have the baby dance every day since. Last Friday, I had had pain in the lower right side about 45 minutes after the Sabbath, a patch of brown mucus. I'm on my period for a week or two, but never before had spotting between my period. Is this implantation bleeding? We have almost 2 years TTC. Could my month?
