Testing DPO

I know its super early, but I also know a lot of ladies have gotten positives just over a week after ovulation. I did OPK so I am fairly confident on the day. I tested yesterday (8dpo) with FMU and this morning (9dpo) as well and both were BFN... Anyone else test around this time and get a BFN, only to get a BFP a week or so later after actually missing AF during the same cycle?
