Does this mean ovulation has happened?

Nicole • Mummy of 3💙💙💗 #4 due October💗

The top one was cd14.

The middle is cd15.

The bottom is today (cd16).

So because the line started to fade on cd15, does this mean that's the day I ovulated?

I was only able to bd when I got the positive test so I hope I did ovulate the day after because maybe I still could have chance
