Give me your secrets to a BFP!!

Another BFN and AF month. I am tracking my cycles with glow and ovia apps, dtd during the window, gave up coffee and alcohol and we don't smoke at all, dh hasn't drank in years. We're both healthy and active and eat well, I take prenatals daily. I'm ready to get (more) serious about ttc. Tracking bbt, ovulation tests, maybe some new apps, whatever. But I'm new to these things since we haven't tried them yet, give me some tips on how to do these or what else we can do to increase our chances of conceiving.
