Ovulation Test

My husband and I have been trying for 3 months now with no luck. This month I have tried using ovulation tests. I take them at the same time I wake up every morning. I'm past when I should have seen my little smiley face according to every app and website. I have yet to see one. Do I keep taking tests to see if it's later? Or is it time to see my doctor? Not sure. It's very frustrating hoping to get the smiley face and nothing day after day. Thanks for any advice!
