Clearblue Advanced OPK

Jenn
Ok Ladies does anyone use the Clearblue Advanced OPK? So my first two days I had a negative and then the next 9 days I had a facing face and then finally on day 10 I get my solid face! MY Question is, is it legit positive? It says in the instructions that it is unlikely your ovulate after day 9... So am I just weird or could it be a false positive? Fyi it's my first month ever using OPK after 5 years of trying on our own so I figured I must not ovulate so this is shocking!
