Thanks for your detailed info!
My sway is very much like how you conceived your boys so hopefully! The only thing I did was cut all refined sugars (I have PCOS so I found that somewhat helped my cycles to be a little more regular but still about 5-6 week cycles) and I didn't get really any sun leading up to O week because we had a cyclone but I did try and get a fair bit in the months and weeks before conceiving.
