Too many details?

My husband and I have only been trying for 4 months now but I've started reading up on things to do/avoid when TTC. There's obviously got to be some planning involved so things are timed right and my theory is, if certain things lower chances of conception then why not avoid those things. My husband however is completely frustrated about facts and figures and would rather go without those details. He's adding pressure (unintentional if it were my doing) and would rather just have baby-making intercourse when we are in the mood. Basically, he'd rather do things the way we used to without contreception. I don't know what to do because I feel like that may take forever. I don't feel like I'm über-facts driven but I do what to give it out best shot. What are your thoughts?
