pretty confused

I have been TTC #1 since April, using OPKs now started bbt this cycle. New PCOS dx, started Vitex this cycle as well. I also work shift work so some of my temps get missed due to working nights but other than that my intake my temp the first thing before I do anything else when I wake up. I sleep pretty restless so try to take my temp the first time I wake up in the night which is generally 3-4am. I had a close to positive opk yesterday a really faint opk last night and now today a strong positive. Since I got my positive today fertility friend got rid of my crosshairs because I have seemed to have confused it. I'm a bit confused too, what do you guys think?
