Having sex prior to IUI

Hey ladies. Iam going to do a natural iui on Wednesday its my first time and my doctor told me that my husband can't ejaculate for 2 days prior to the iui. I was wondering has anyone successfully gotten pregnant even though you all had sex the day prior to the iui? It just seems weird that they want us to skip a valuable day of sex as I know the more days you have sex during the fertile window the more likely you are to get pregnant.
