New here....going to do IUI next week, any advice?

Hello ladies, 
​I'm very excited to have found this community especially today. My fiancé and I are undergoing IUI this coming week. We have been trying for about 8 months and after testing for both of us, it was discovered that his morphology is 0%. We were devastated but have some hope with this IUI option. I am 38 and he is 33 so I'm definitely feeling the pressure of time running out.
​Anyone had an IUI? Any success stories? Any advice on what to do before or after the IUI? Any advice at all would be so welcome!! 
​Thanks in advance!!
