Help first time using ovulation test

Em

We have been trying to get pregnant a second time for over a year now, so this time i decided to try tracking when i ovulate. But i havent got a clue how to start. I am on the second day of my period, so what day should i start testing after my period?,Once a day? I have been reading about that it has to be as dark ir darker than the control line so when i see that do we bd the same day i see that?, and after that do i keep testing or do i stop till after the next period ends? Sorry for so many questions.

Thank you all
