can you change thermometers mid cycle? mine was acting goofy this morning.I thought it temped wrong (it came out 97.11, then 97.10, & 97.17) but when I got up & used the regular thermometer it said 97.1 so I gues its right. it was not wanting to come on right. I think the battery is dying b/c I've had this one for about 3 years. I was just wondering if you get a new on if it will mess up charting in some way
Re: changing thermometers
I have two BBTs. One reads almost an entire degree lower than the other, so if it were me, I'd wait until next cycle to switch.
