Ovulation testing

Brittney • 👨‍👩‍👦‍👦💍💘

I need help lol I’ve never used an ovulation kit before & I’m super confused. I usually have 29 days between each period, & am usually on my period for 7 days.

So I started on Sept 30th, & should be finished on the Oct 6th, when should I start using the ovulation kit?
