First IUI

Due to male related infertility my husband and I have decided to try IUI with donor sorry. I’ve checked out ok so far (even though I had unexplained infertility my first go around and needed Clomid). But this time is different. I’m 40. It’s been almost 7 years since I’ve been pregnant. I’m just scared of the possibility this won’t happen for us.

Please can I have some reassurance from those who have been in the same situation. Also would love some feedback on the process
