What does it mean when the test line for ovulation test starts to get lighter?

I feel like it’s getting a little lighter. I’ve take three today. The last one was just now and the two above were from earlier today, obviously positive but the last one doesn’t look the same. Does that mean I ovulated? Or am ovulating soon?
