@peachiekeen it's a method another poster (Purple) got recommed and it helped some posters to get a BFP.
It's basically forgetting all opks if you're +/- regular and going off your guessed ovulation date. It's basically DTD o-7 and then nothing until o-3 so the sperm will have time to replenish. Then again o-1 and o+1 in case you ovulated later than usual. It's kind of a SMEP light version :)
