What test strips are you using? It's the first time I am hearing about that, I guess it's not common in Germany.

I/we track it, mostly because she is a bit clumsy and forgets when her last period was & when the next one is. So not for ovulation tracking at all. Once she told me she thought she was pregnant because her period still was not there; I checked chats & the app and could confirm her period was still two weeks away :).
