Thanks Tanya. Im wanting to get quite an accurate O reading for girl swaying, and previous to this last pregnany, I know my cycles can vary a fair bit. FF never had me convinced, as it would put my Luteal phase from 11 -14 days (usually 12 days). Im not sure about the hassel of pee on a stick ovulation things, last time I tried using those a few years ago I went through quite a lot with no luck (probably due to the variation of 26 -35 day cycles...) Hmmm, looks like a busy road ahead with this swaying business
