Big fan here! I ovulated later than I thought! 12 months TTC-ing without, 6 on the CBFM then BFP, 1 cycle on it and BFP (sadly mmc) - using it now. I love the feling of control it gives you. In our case we both work long hours and have a 3 year old so DTD needs to be timed well :)
If its any consolidation they have a hgh re-sale value
God luck!!
