What did you do to conceive?! Any old wives tales?!

We've been ttc 8 cycles now. I bbt, use opk, use preseed, take vitamin B6, B12 and prenatal vitamins daily and started Vitex this cycle. Also have been on progesterone the past 2 months from 1 DPO- period and started drinking pomegranate juice. Also ate pineapple after ovulation last month. We BD 3-4 times during fertile window. What gives??? Are there any other little tricks you feel like did the trick for you? TIA!
