Maybe this is a "you know you've been TTC for too long when..." moment?

Has anyone's BBT died? How did you know? I thought it was a while back but my charting was fine. Then the speaker thing went so instead of a loud beep at the end, it makes this dull, sick-sounding beep, lol. Well, now I know my temp should've spiked today or so (did trigger shot Sunday night) and it didn't. Nipples are sore like usual post-O time but I don't know if that could be a side effect of ovidrel? Awesome timing BBT.

So really - those who temp and have replaced their BBT, when did you know you needed to?
