Just don't even understand.

So yesterday got a positive OPK, (wrote a post for advice) with First response, even took 2.  Later that night, probably around midnight, hubs and I decided to go grab some different ones. First off I used it wrong, your supposed to insert the stick then pee on it, but the clock did still work and came back with a NO! Has anyone used these before? When I google it for any info, NONE. To say the least I was highly upset. I did BD just in case.. Just wanna know if anyone has experience with these OPKs. Sorry for the long post!
