Implantation bleeding??

I’m around 5 DPO. I am having some light bleeding this morning. Could this be implantation bleeding? Or is that too early? I have had 2 successful pregnancies, and 2 miscarriages and I have never had implantation bleeding. I am also a little confused because I got a positive ovulation test on 8/15, but then this morning I had this ovulation test. Does this one look positive too? Not sure what is going on!
