This is slightly unrelated but having taken both FertileCM and EPO I would not recommend taking both.
Personally, I think either one works but not together. Fertile CM did not work for me, dried up my CM completely. EPO works for me and I got prego using it in Nov. But I know others swear by fertileCM....its an individual thing.
But yes, all the HE diet and supps definitely messes with ovulation and cycles, which is bizarre as we are increasing fertility which you would think would keep our cycles on a set pattern.
FWIW, when I know AF is due and I have some symptoms and a BFN I use the heating pad and that usually brings it on. I feel like that is the least crazy thing to do but still works.
