BBT and CBFM

[jb129]

I'm 34 and DH is 30. We've been TTC for a few months now. I've been temping and using the CBFM and both almost always coincide - so every time I get a temp dip on my BBT, I also get a “Peak” on the CBFM.

We BD every other day (evenings after work) when I get a “High” on the CBFM, on the day of Peak itself, and day after Peak.

However, even though everything looks “normal”, we’ve not gotten pregnant

1. Are we BDing at the wrong time of day?

2. If you measure BBT and use CBFM, does that confirm ovulation at all? Or are there other factors that may cause for one to not get pregnant that these 2 methods, even when used simultaneously, are unable to determine?

Here are my charts the past 3 months:
