first response digital opk kit

Trace • I have a 18 y.o. Boy. 13 y.o. Girl. Ttc since 2015. Miscarried Mar 2016/May 2018/Oct 2019/Apr 2020/Apr 2021/Nov 2021/Aug 2022/Dec 2022/May 2023. Ttc our 🌈 baby.
I just realized that they are a one time only thing. Once you get the positive opk which I did this past cycle they then shut off permanently! Their not cheap and I still have test strips left! Anyone else find this brutal? And is there any other opk you ladies recommend?
