First time using OPKs and I need help

So I know there’s a group for these questions and I posted there yesterday but got no help whatsoever so I’m hoping someone here can.

I’m using the Easy@Home brand and when I took a picture it says LH- High 36. I know its not a positive so I won’t ovulate in the next 24-48 hours (or whatever the time frame after a positive is?) but does this mean I’m in my fertile window? The last day of my period was the 4th. 🤷🏼‍♀️

Also sorry about the quality of the photo.. I tried several times to get a good one but couldn’t keep my phone steady and the lighting in our bathroom isn’t great.
