Best ovulation tests

Looking for recommendations for ovulation tests. Any brands recommend/not recommended? The only ones I’ve been using are the clear blue advanced. I used them in September and this month.both months I didn’t get a peak- only high fertility. I know I ovulate because I got pregnant in September (ended in Mc). Im assuming I stopped taking the tests too early. I had 9 high days -and honestly gave up and stopped taking them. I feel like I’m just having sex on the wrong day’s because I’m basically guessing my ovulation date😕
