I may be mistaken, but my understanding of most of tracking is supposed to be so that you know when you are most fertile, and therefor most likely to conceive - and therefor the most "productive" time to have sex?
I realize this is conventional wisdom, but it seems to overlook the fact that if a man only has sex a couple times a month, he will produce fewer sperm (and those that there are are less likely fresh and vital). Also that preeclampsia is minimized the more the potential mother is exposed to her partner's semen.
In other words, its probably counter-productive to "save" sex for only those couple days before and during ovulation.
Having sex as much as possible (as long as its still pleasurable and fun) isn't a waste, it should actually make reproduction more likely.
Now mind you, I just made that up, because it makes sense to me, but then I asked Google, and the internet (and the doctors and specialists it quotes) agrees:

Unless its been more than a year, and/or there is a
specific reason to think there is a underlying medical issue, and/or the lady person is over 35, I don't think there is any good reason to do much special besides have lots of sex (and take enough folic acid!)
Of course in America all problems are solved with drugs and specialists and stuff, but the Mustachian way coincides with the way animals have been doing it for the last 500 million years.
Lastly - (and note, I'm planning to have kids too, so don't take this as judgement)... Lastly, if it doesn't work, maybe that's ok too. There's a lot of humans already, and a good number of existing kids could use homes. Adoption can get you all the rewards (and stresses) of parenthood, and there's a lot more to a family than just DNA
