HELP Clomid and opk

Jaci • Trying to conceive my first child. I`ve had one miscarriage. I also have pcos and a hypothyroid.
I'm on my first round of 50mg of Clomid, today is cd 15 for me and I took Clomid cd 5-9, I started using the clear blue digital (not the advanced) ovulation kit cd 12, my question for you Clomid ladies is, when did you see your positive opk? I'm starting to get really discouraged 😔
