Thermometer dying? 🌡 🤒

Hi!

Quick question - I have been taking my bbt every morning however my temp seems super low/doesn’t change much from day/night (been experimenting lol) I only chart my resting bbt when i first get up though! However it hasn’t indicated ovulation.

Today I took it before I got up (97.21) after getting up, getting ready, etc, I decided to take my temp again... it was at 95.31. Before bed it was at 97.01. Do you think my thermometer is dying? This does not seem accurate to me. I have never had a problem previously.

Please let me know what you think!🥰

Thanks!
