Unexplained infertility

I have been ttc for about 14 mo and at the one year mark I went to see a fertility specialist for testing. Our test results came back normal and the doctor said there does not appear to be an explanation as to why it's not happening. At first I thought I had a low ovarian reserve but this did not appear to be the case. My husbands sperm count/motility was off the charts high. Super frustrating!!! The doctor suggested trying naturally for another 6-8 months and then trying

IUI

with a trigger shot. I'm currently doing acupuncture and going to see a naturopath soon. I also eat clean, exercise and have been doing so for years. Using preseed, vitamins and the cough medicine ingredient to help cm. Any experiences with this or any suggestions ?
