Should I expect two days of positives this month too?

So I had 24-36 hours of BLAZING positives last cycle. Confirmed with temp and got af 15dpo. Should I expect to have two days of blazers again or what? Only second month using opk’s now. Wondering if I should be testing twice a day or if that will just waste my strips as I got 2.5 days of blazers. Advice? Thanks!
