Complicated question

So, I was diagnosed with PCOS about three weeks ago and was put on Metformin. I haven’t had a period since the end of August, but I began tracking my OPKs and started to see them get darker over the last two weeks. I have an appointment to see my gyno on Thursday 11/8, which she said she would prescribe me Provera and Clomid if I hadn’t gotten my period yet. I am trying to figure out when I first ovulated to see if she will hold the Provera in case I could have gotten pregnant. If I ovulated on 11/1 like I think I did, it will be to early to know if it was a little sticky bean. I just don’t want to take Provera if there is a chance something could have stuck. I’m trying not to get delusional that I got pregnant on the first try with meds but I don’t want to take meds that could hurt either. What do you guys think?
