So this is just a subject that I have been curious about for several years now. Practically everyone knows someone who managed to get pregnant while on the pill. I know at least three people it has happened to. At least in the cases I know about, I'm sure they were not taking their pills properly, so their protection was lowered.
What I have always wondered, though, is if the usual fertility signs appear in these cases? If you happened to be temping, or paying attention to cervical fluid, or checking your cervix position/texture would you notice changes that might alert you to the fact that your birth control was failing? I've always wondered if you could "catch" yourself, as it were, and take precautions based on physical signs. Ideally, if you knew you had made a mistake with your pills, like accidentally skipped a pill, you would add condoms or take other measures to avoid pregnancy until full protection had been re-established. But does anyone know if you'd have any of the physical indications that you were about to/had ovulated?
I've always been pretty good and consistent with my pills, but since I do know a bit about charting, I always wondered if I could maybe just watch for EWCF in case I did screw up, and have that, or other physical indications to be careful.
