I’m having a hard time with getting accurate readings on my thermometer. For example, today I got a reading that was exceptionally low. I redid the reading immediately after and it jumped from 98.11 to 98.29

After this I was really confused because that’s a HUGE difference. So for the heck of it, I did it again and got 98.60.

By now I was just tired and frustrated so I took a few more readings and got 98.27, 98.20, 98.25

I understand the longer I’m awake and the more I move etc. will affect my temps. I’m temping the same time every morning (5:45am; never past 6am), temping orally, and getting good sleep.

So my questions are: is this just a thermometer issue? Maybe battery? (This is the second thermometer that’s started acting up — the first one was waaaaay worse off you can believe it but I knew it was busted because it was only taking a few seconds to register and it used to take a full minute)

Is there a thermometer you recommend?

Should I maybe switch to vaginal temps next cycle for better accuracy if this cycle isn’t the one? (Crossing fingers though! 7-8 dpo today!)

Any tips or suggestions would be awesome. Thanks so much!
