Temps. While for some women they may not be reliable... thats estimated to be less than 10% of women. Progesterone really DOES raise your temp once it is in your system. Ask any woman who has used progesterone... if they dont use it as of O day (its best to wait to confirm O before using it anyway as progesterone before O can hold off O and cause you to be anovulatory) they will see a temp rise once they start using the progesterone, likely a second temp rise after the one they already had from O.
EWCM can be there but not be visible. It doesn't matter if you are gushing EWCM like Niagara Falls... it doesnt matter if its all around your cervix when you check inside either... all that matters is its up in your uterus to guide those spermies where to go (and once you start DTD some EWCM from in your uterus will leak out to help clean off and guide the spermies... even if there was no sign of it pre-DTD.
OPKs only tell you if your LH is surging. You can miss the surge, surge and ovulate 3 days later, or you can surge and not ovulate at all. They are a good warning sign that ovulation may be coming but NOT something to trust as a sign that ovulation happened or when.
