Questions and frustration

We started ttc Nov 2022 and started tracking cycle January/ feb 2021 no luck so my husband had a SA august. His results were bad, low motility, low morphology. We did a repeat per the request of his urologist in November. He made changes drank less stopped smoking marijuana , took supplements and his results are great, 90+ million count greater than 50% progressive motility morphology was lower side but both doctors said it’s nothing to worry about. We’re still not pregnant, and diagnosed with unexplained infertility …..when thinking about statistics and trying to make ourselves feel better …. Should we focus on the months ttc where his SA improved? I’m just so impatient, frustrated with no answers, losing hope
