Ovulation advice

D
It has been 4 months since I stopped taking bc to start TTC with my hubby. He has been very supportive in getting ovulation tests and reminding me to test in the morning and just trying to keep up my mood. I haven't had a positive ovulation test in the 4 months since I stopped bc. Is that normal? Or not? I have been having regular periods that are heavier than when I was taking bc (so starting to look normal), but no poisitive tests. Just looking for any advice or others experiences to know if this is normal and if I should just be patient and wait.
