Clearblue Digital Error

Hi everyone! I’ve been taking the clearblue digital opk tests twice a day, and yesterday and this morning I received a high fertility result. I just took my evening test and got an error message (I think the test was not wet enough). I’m trying not to miss my peak fertility window, so I’m not sure what to do. Do I stay up another 4 hours and test again, will that even be as accurate? Here’s what the test looked like when I tossed it. Thanks!!
