Positive opk

Amy • Mom to a sweet baby girl, our rainbow!!
Hi all..! I am 5Dpo today, but I'm still getting faint positives on my ovulation test.. That is there still a faint second line even six days after my ovulation.. I saw that my test shows completely blank in the next two daysof my ovulation, in my previous cycles.. But this is new to me.. Does this happen to anyone else...? Plz share if I need to have any concern due to this..does it indicate any ubnormality in my ovulation??
