I use clear blue digital advance with the smile faces to track OPKS, I have 4 strips left from the box I used this past cycle that I want to use next cycle ..

either way I was prob gonna buy a whole new kit this week ( since I can’t just buy more new test strips) but not sure if I can use those test strips on my old test holder ? I think you can.. but some people say your old holder won’t be as accurate since it detected last cycle OPKs? Is this true ?

I have 4 more strips left with my old pack and if I can maybe get away with just testing for the 4 days till I get my peak might not even buy a new pack?

What do you think? Shit ain’t cheap! 😅

Thanks!
