Help with clearblue!

So I decided to start using these. Im on cd 9, which is when the chart told me to start testing. I know the box says to test after your longest sleep. But I’ve been reading and some people say it’s best in the evening? I’m new to tracking things like this. We’ve been trying for a year with no luck, so hopefully this helps. Also, I saw where with these tests your not supposed to look at the sticks, just the results? Sorry for all the questions, new to all this and want to make sure I’m doing it right Haha
