I started my opk testing for cycle day 9 and I got a negative. I’m trying to stay encouraged

So I finally picked up opks and it just started testing and I already got a negative as far as ovulating or testing the surge they’re looking for. I’m really praying that I will get a positive.

Does anybody have any advice or anything? Should I test twice a day?

I’m praying for a positive this cycle. We’ve been trying since June of last year
