Ovulation test

MinAdah

Hi guys. I am so new on this ovulation test. We are really trying a for baby this cycle after a misscarriage my 1st baby in june 2017. Up till today we are still trying. So this is my first time tracking my ovulation using the test. From the picture i start tested on 3rd-5thfeb. On the app stated I ovulate between 1st-7th feb. From the test, does 4thfeb is my most peak period? That i should be BD?
