First IUI tomorrow

Hello all! I have my first IUI tomorrow morning at 7:30 am. My hubby and I are both excited and very nervous. Can anyone give me an idea of how long the whole process takes? (Sperm washing and everything) I’m not working at all tomorrow by my hubby was wondering what time he should tell his work that he will be coming in? Also any tips on staying calm? I’ve already cried twice today because I’m so nervous and just keep telling myself it won’t work 😔 thanks! And baby dust to everyone!!
