Ovulation test strips

Hey ladies! I just ordered ovulation test strips from Amazon but I've never used them before. My husband and I have been ttc for 2 years and my periods have always been regular so I just assumed I'm ovulating. But I wanted to go ahead and get the tests because we haven't had any luck yet and i don't want to miss our window! Haha I just have one question, when is the best time of day to test? I've heard some people say first thing in the morning isn't good because lh levels are low but others say anytime of day. What has been the best time for you? Or does it matter?

Thanks in advance, and baby dust to everyone!
