1st failed IUI

TTC4BFP
Ladies I'm super depressed right now. My husband had 6% morphology excellent motility for our IUI (80 percent) 32 million count post wash. I was so nervous yet hopeful. 
Tell me, with these number, would you go for IUI #2 or straight to IVF
It's just heart breaking. I'm really scared to have such a low percentage again. :( 😪😓😢
Please, shed some light on this subject if you have any experience with a bfp via IUI and morphology issues. I have no problems what's so ever... ovulate on time and normal levels 
Thanks for listening .
