Can ovulation spotting turn into implantation bleeding???

I had a peak on opk on the 6th of this month. On the 7th I noticed that I had started to lightly spot. The spotting was orange which is normal to me, this kinda of spotting continued while varying from light to medium until Friday( the 12th) when it was a medium spotting but it turned pink. The only reason I Considered it medium is because I saw it every time I wiped, not because it was a lot. That went on until Sunday night. This morning I woke up and only had one spot of blood. I have never had pink blood come out me before. If I spot it always orange.
