Ovulation test

I had my last Depo shot in January and my cycle has been pretty consistent starting May I had a positive ovulation test in the middle and then a period at the end of may and then same for June positive ovulation test in the middle and period at the end. I thought it would be the same this month but it’s my ovulation week and I haven’t had a positive ovulation test I usually take one a day during my ovulation week. I thought maybe I just missed it but now I’m wondering if I’m not fully off the BC sadly.. any similar experiences?
