One follicle for iui

I had my follicle scan for my <a href="https://glowing.com/glow-fertility-program">iui</a> today and she said I had one mature follicle on my right ovary. She didn’t say the size but I’m thinking the 23 is the size. Is only one follicle ok? I mean I know it only takes one but I was expecting there to be more with clomid
