Extreme low BBT temps this cycle. Faulty thermometer or thyroid?

I think you’re looking into it too much. The thing you’re looking for is the temperature shift not the actual numbers. 

 

You could be having an off cycle, could be that you’re stressing is delaying your ovulation slightly.

I don’t see a difference really from prior months? Your first half temps are typically between 36.0 and 36.4. No difference this month from what I can see.

greywacke :  Do not compare your temperatures throughout the day to your BBT first thing in the morning.  It looks like you possibly haven’t ovulated yet.  Sometimes women have anovulatory cycles, or your ovulation is just delayed.  I agree with PPs, you’re probably overthinking this.  Not every cycle is always the same.

To check my thermometer, I usually sit on my bed or a couch for 30 minutes… then take my temperature about 3 times in a row without moving to see if I get about the same temp.

It looks like you haven’t ovulated yet and the Tuesday temp must have been a fluke..

Tired adrenals can result in a low BBT also

Are you taking your temperatures orally? Oral temperatures often give a lower temperture because of the wet environment and air flow. You’ll get better results if you take vaginal temperatures because this will give you a more accurate core temperature reading. That being said, my core temperatures are often around 36, particularly first thing in the morning, because this is when your metabolism is lower, and you’ve been less active

greywacke :  your temps aren’t super low. You haven’t had a temp shift this month which means you haven’t ovulated. It may mean you won’t ovulate this month, resulting in an anovulatory cycle. That happens with PCOS, at times more often than not. If you’re worried about a faulty BBT go ahead and grab a new one and see what it does.
