buying things when starting IUI

Hannah
My SO and I have been trying for 2/3years, because he has cystic fibrosis there is only 2% chance that his swimmers work. Today we found out that he can't conceive. 
We are getting referred to a fertility clinic in the next few weeks 🤞 
My question is would it be bad luck to start buying things/ decorating? 
I'm completely health and have a regular cycle so when we get a donor we shouldn't have an issue 🤞 thanks for reading 😘 xx
