Low morphology

DH has 1% morphology. We went through several rounds of natural cycles and 1 iui. However insurance does not pay for IUIs. We are taking a break from seeing our re for a little while. How long did it take before you were able to successfully conceive naturally? Ivf is completely out of the question and I can not justify paying for another iui. Morphology is the only number low and my cycles are so regular teaching hormonal middle schoolers doesn’t even mess it up. 28 days on the nose every month.
