Opk question

T • Mama to a miracle🌈 6/8/21

I’m pretty sure I ovulated the 6/7th as I had + opk and then elevated progesterone a few days after. However, are the opk’s supposed to stay dark (but still negative) or fade and get lighter post ovulation?

Also- the bottom on 2nd pic is only so much darker bc it’s still wet!! Thx
