Help with ovulation day

Anfal

Hi ! i’m trying to conceive for my baby no #1 now after break from trying for a year .. I was using the pull out way during that time . According to this app I should ovulate TODAY.so, I took digital ovulation test (clear blue) and it shows circle with out smily face thats mean I have low fertility today(not high or peak) than I added this info here in the app and it changes that ovulation day to 4 days after .. now I’m lost when should I use the ovulation test again!?? 😅
