Progesterone levels and possible Implantation spotting?

Lauren

I’m 6 dpo with a very strong positive OPK at CD14. Had sex on CD 13 and CD15. Last night at 5 dpo I had some light pink spotting after sex. I also just received progesterone level results which were a 10 at 5 dpo. Does anyone have any insight on what this could mean? Am I just getting my hopes up for no reason?
