Cycle day 9 follicle scan on Letrezole🤞🏻

I know cd 9 is pretty early on and my appointment is just 2 days after I took my last pill butttt what should my follicles be at by then? Over 10mm already orrr? I tried 100mg clomid for a round and i didn’t respond at all so I had none bigger then like a 9mm☹️
