Clear Blue Advanced Digital OPK

Last month I only had to use 4 pee sticks before getting my solid smiley. This month I thought, great, I can use the left overs... But then I just thought, will I need to get a new packet so that the digital part is new or can I use last month's?

I found the a see on their website - it said the digital part can be re-used.

I used the Advanced Digital ones and found them really unreliable. I had a flashing smiley face for days on end and never got a solid smiley. After Googling them, I found so many bad reviews about them.
I've gone back to using the Clear Blue Digital OPK (not the Advanced one).
Good luck!

No you can use them over multiple months, you only need a new digital when you're out of sticks.
