We do a variant of it, I suppose, as I have no idea when I ovulate. Basically we just dtd every other day from cd10 to cd30 and hope we catch it. It hasn’t worked yet though!
Have you tried earlier than CD10? I ovulate 3-4 days after my cycle ends. I figured that out when I got pregnant with my daughter and then now trying for #2, I use the OPK and they confirm it’s within CD 3-4 and actually just got pregnant but unfortunately it was a blighted ovum
