Anyone had IVF round canceled due to dominant follicle and convert to IUI?

Cheryl
I am on day 6 of stims and u/s showed a dominant follicle and the others were not so big. They gave me option to continue so we are and we do the shots tonight and tomorrow and then a scan Friday  where we will probably convert to IUI. I don't want to waste my one or two eggs since I have low egg reserve. Anyone had this happen?
