I am having similar problems. Does stress affect your ovulation that much? I'm hoping so because I have been SO stressed out this past month and am now on CD36, with no ovulation still! I have ewcm as if I'm gearing up", but no continued temp shift.
i'm nearly certain it's my stress. i've been worked up for PCOS - negative. all my other tests thus far are pretty normal and i ovulate easily with clomid. with this cycle, i wanted a clomid break, and kind of wanted to see if i'd ovulate on my own. guess i got that answer! nope! breakthru bleed started CD54.
my job: i'm a surgical resident, in charge of a busy orthopaedic trauma service, working routinely ~80hrs/week, and often (about every 3-4 days) am on call and at the hospital for up to 36 hours at a time, depending on how busy it is that night. my ovaries do NOT like this schedule! thankfully it's almost over. :)
