Blotchy OPKs?

Has anyone experienced this before? I should be ovulating either yesterday, today or tomorrow, but I’m not sure if I should consider these blotchy OPKs. I usually have no problem with this brand, but as you can see, it’s happened a few times. Should I still consider them as accurate?

Close up of blotchy OPKs

The one on the bottom was pretty close to the 5 min mark. The second from the bottom was taken maybe 10 mins from the time I took the picture. The one on top was from earlier today. I know you can’t go by them if they’re older than 5 mins.
