One egg IUI?

So i am supposed to have my first <a href="https://glowing.com/glow-fertility-program">IUI</a>. I am ovulating ok, my egg count looks ok, the sperm ok too. I had a brief talk about it with the gynec but everything is postponed until after this corona crisis.

Maybe it’s a stupid question but i couldn’t find the answer. Can this be done using just one egg? I only want one baby. She mentioned something about making an injection to make sure i ovulate or to know when i ovulate, can’t remember exactly, but she said no other treatment is needed. Thank you
