Clearblue digital ovulation kit accuracy

Charley • Married and pregnant with #2, a second girl.
This is our first month TTC. I charted last month and had a 36 day cycle, however I'd just come off the pill. Decided to start using opk yesterday on day 11 because I felt weird and wondered if it was hormonal, but got a low fertility result. Today I get this. Should I trust it?
