Late o... Help!!

I'm on CD32 and still waiting for o. I obviously have PCOS and went to my re for the first time last week and with the us she said I had a follicle that looks like it would o soon. Think it was 17mm. I finally got a pos OPK the other day, but I have never taken this long to o before. Has this happened to anyone else? Did anyone get a BFP when o'ing this late?
