3 months ttc at 40-IVF time?

Hi all-
My husband and I have been ttc for 3 months. Doing tons of supplements, opk, timed intercourse and acupuncture.
I consulted a fertility specialist about 5 months ago and he suggested trying for 3 months then considering intervention because of my age.
I'm not thrilled with the idea of <a href="https://glowing.com/glow-fertility-program">IVF</a> (my husband is especially not keen). But I don't want to waste time and we are lucky to have fertility insurance. Thoughts?
