I read that stress doesn't interfere with TTC, which makes it a myth. But if we think with our brain, doesn't stress ruin our AF dates? It does.
I went once to see my doc before TTC, and he told me and explained how our brain affects conceiving, and it does make sense.
I stopped charting my CM, and testing for ovulation, bec they did make me stress and irretable. I went to TTC the natural way and it happened that month.
Quitting charting, and other TTC obsessions can reduce ur stress. Try it, what if it works for you? It did for me.
When my doc gives us the green light to TTC again after our second miscarriage, I wont charge anything, neither test for ovulation, but maybe will check only my fertile week so that I know when baby dancing should happen the most. If u wana know where to calculate it, check it here

Good luck!
