Extra sticks?

Elle • 👼🏻 35+3. 27•07•22.

Can one of you please help me figure out the Clearblue Advanced Ovulation tests? I used a new package last cycle and had two sticks leftover from that. So this cycle I took last cycles holder and used 1 of 2 remaining test strips. Can I use test strips from a new box with the last cycles holder? Or does each holder only work for 10 tests.. i hope this makes sense. The cost is daylight robbery so I don't want to f it up lol. Help please 💛
