Fertility Monitor accurate?

I am using the CBFM. I had highs from cd7-13 and my first peak at 14. This surprised me as I usually have cycles of 30-35 days. I am now on cd32 with no sign of AF or a BFP. Does this mean the CBFM is incorrect? We only BD'd on the last high and first peak day so I suspect we will have missed the egg if this is the case. Thanks
