Possible IB help

I’m not sure if this is the right place to post this, but looking for advice! I’m believed to be 8dpo, period isn’t due for another week or so, and I had some VERY faint pink blood when I wiped yesterday, lasted from lunch time til dinner then gone. Nothing today. NO cramps or other symptoms besides a possible increase in appetite and BARELY there breast tenderness. Also to note, I had a VERY late ov and I am on CD 33 of a usual 35ish day cycle if that matters. Thanks for any help!
