I used to get so stressed too, DH was telling me to stop swaying, as all the mineral counting was probably making me sterile with stress :) . I think the problem is that these issues are not discussed properly over on IG, so people are just feeling like failures when they might be trying for the impossible. I only measured CM pH a couple of times, I always had something like 6, which is why I felt better measuring the mixed pH on the day. That's the only thing that matters anyway.
