Taking temp twice?

Kimberly • Married to my best friend, finally pregnant after 2 years TTC! Due April, 2021. Our furbaby, Indy 🐾 finally gets a best friend!

Hi all! Do you guys ever take your temp back to back? This morning I got 97.23 and then immediately after 97.48. Does this mean something is wrong with my BBT thermometer? Should I always use the first temp? Thanks!! 😊
