When i was on Clomid i also didnt do FR i tried to dtd once every day around o time and on so no messing with anything,just trying to get pregnant while on it.and i did on my 3 rd round of Clomid,but i had been on the diet for the whole previous year almost ,and had started out with FR in the early days but dropped it all,so i would recommend diet over any technique or frequency :)
