What size were your eggs for IUI? Is 21mm and 25mm too big?

I had two eggs at 21mm as 25mm for my <a href="https://glowing.com/glow-fertility-program">IUI</a>, that seems big to me but my doctor said they were good? I trust her judgement, but I feel like I hear most people being around 16mm-20mm.   Could mine be too big for fertilization?
