Bizarre symptoms? Any insight?

Something off is happening. I had some very light spotting today. Just brown dried up stuff only present when wiping and my temperature has gone down the past 3 days on my app but I’m only like 6 DPO and I never spot. I’m not sure what to think but I am worried I may just wind up getting my period early. I don’t think it is implantation of anything like that because that would be super early? Does anyone have any ideas? Nothing is really different this cycle as far as my lifestyle
