Implantation bleeding or something else

Me and my partner have been ttc for awhile now. I track my ovulation through glow and clear blue advanced. I received a peak 3 days ago, so my LH surge was detected. I know it’s early but I’ve been having light pink- brown spotting all day. AF isn’t due until the 26th of October. My question is do you think it’s to early to be experiencing implantation bleeding? If so what are your suggestions?! My fingers and toes are crossed that this is our month
