TTC - NO LH SURGE OR YES

My husband and I are trying to conceive and it’s been a struggle which I think is from me using depo-proverá for 4 years and stopped 2 years ago.. I’ve been taking ovulation tests but I’m sure it’s not positive but he says it might be. I doubt that. Anyone have better ovulation test recommendations?? I’m not sure how I feel about this clearblue one
