Ovulation/PreSeed/🍍?

Okay so I started my period this month it was from March 6 - March 10th & according to Glow I'm suppose to be fertile tomorrow starting on the 15th. So what would be a good time to start using this preseed? I used some yesterday but just curious & can I get some more info on this pineapple stuff?

Oh and should I still take a ovulation test today or tomorrow?
