So what happens if you use expired LH sticks? The reason I ask this is I bought a Luna Fertility kit because it was on sale at my grocery store. And when I got home I saw that the LH strips had expired in March. (probably why it was on sale) No big deal because I really bought it for the bbt thermometer and the how to booklet. Heck I guess even for the saliva thing.
