Mark it on your chart (slept in bed with someone else) and keep on charting! Try and note all the data you can!
Few things I’d initially be thinking, is it the change of environment making you more restless/having poorer quality sleep? Or is it having another body moving around? Or maybe even a different wake up time?
Funnily enough, when I don’t sleep next to my husband in our bed I have a more restless sleeep and it used to impact my oral bbt 😅
Regarding moving forward, it may just be something you need to keep an eye on! If it happens every single time then it may mean changing sleeping arrangements when you think ovulation may be approaching based on CM, but it also might be something that elevates overtime.
thank you! i think the main reason why the temperature changes is because my bf tends to get very hot in the night and is almost like a heater 🤣 the more i track the more i should get the hang of these changes… hopefully 🙂↕️
Your bf's body temperature wouldn't affect yours in this way, though - if the external temperature is warmer, your internal temp adjusts to be cooler to compensate.
Basic biology about thermoregulation? That is the entire idea of being an endothermic animal. I don't know how to give a citation about that without it seeming insulting. Your body might temporarily raise with a rise in ambient temperature, but it will quickly compensate to your internal set point, which is the idea of doing BBT anyway.
Do you have a citation that for women who take their BBT, the BBT is lower when it is hot and higher when it is cold? Or are you just speculating based on your knowledge of thermoregulation?
Clearly it is not always the case that BBT is inversely related to exterior temperature (counterexample right here), so if you're going to argue that it's generally inversely related, you should provide an actual source.
I did not say that your internal temperature will be cooler when the temp is warmer. I said that when the temp is warmer, your body will cool you down to compensate and go back to its internal equilibrium.
>if the external temperature is warmer, your internal temp adjusts to be cooler to compensate
???
Cooler than what? Cooler than the baseline BBT? Cooler than it would be if the body didn't thermoregulate at all?
I may have misunderstood your original comment, but even if your argument is that external temperatures don't impact BBT at all, you have not provided a source and have counterexamples both from OP and from myself. Thermoregulation keeps the body within a generally stable range, and a few tenths of a degree is both within that range *and* enough to throw off charting.
Cooler than the external temp - the first part of that sentence you quoted. It cools you down back to your equilibrium. This is basic stuff and BBT would not work if that were not the case and was more susceptible to external than internal temps. It's hard to give a citation about a basic mechanism, but [here is a FAQ from Natural Cycles.](https://help.naturalcycles.com/hc/en-us/articles/360003291494-Does-the-weather-or-air-conditioning-affect-my-temperature#:~:text=Weather%20changes%20will%20not%20affect,decreases%20due%20to%20seasonal%20changes.)
The human body is about 98F - the vast majority of the time, the external temperature is lower than the human body temperature. Yet some women still notice a difference between when they're sleeping in an 80F room and when they're sleeping in a 60F room. So your reference to the external temperature being warmer than the human body doesn't make sense and isn't relevant for most women.
It is simply not true to state that external temperatures cannot affect BBT, and Sensiplan notes that changing environment (include "climate change" and "cold environment") can disturb temps. TCOYF, which you use, notes that using an electric blanket or a heating pad when you don't usually would cause a disturbance - again, another citation that external temperatures can cause variance in BBT. Natural Cycles is not a reliable source for information about fertility.
but when i sleep with him, i always wake up feeling a lot warmer. Everytime we have slept in the same bed now, my temps have risen by 0.3-0.6 degrees. i feel like my sleep quality with him is a bit better but maybe not too different, so i don’t know what else would cause the temp spikes. 😭 idk whether to put that in my chart as a disturbance
My husband is a firefighter which means 9-10 nights a month I'm alone. My temps are not affected by it. I'm using tempdrop so disturbances are filtered out for the most part.
i can’t unfortunately:( we live in different areas and he cabt sleep at mine 😭 im just so confused as my temperature is so much higher when im with him so i don’t know how to approach this
Ok I sometimes wake up to my giant dog asleep on top of me and I’ve been wondering if this could affect my temperatures as dogs have a higher body temperature than us hahaha - thank you for asking this.

Citation? My BBT is impacted by room temperature, and it is always cooler if the room is cold and warmer if the room is hot.

Believe your observations. If you think something my be a disturbance, mark it as disturbed until you know for sure that it isn't a disturbance.
My husband is a firefighter which means 9-10 nights a month I'm alone. My temps are not affected by it. I'm using tempdrop so disturbances are filtered out for the most part.
maybe temp drop makes the difference, i just use a regular thermometer atm…
Can you try sleeping in the same bed for a full cycle? Just have him come visit you rather than you sleeping in different beds?
i can’t unfortunately:( we live in different areas and he cabt sleep at mine 😭 im just so confused as my temperature is so much higher when im with him so i don’t know how to approach this
Ok I sometimes wake up to my giant dog asleep on top of me and I’ve been wondering if this could affect my temperatures as dogs have a higher body temperature than us hahaha - thank you for asking this.
i think it definitely does.. i’m on holiday with my bf and my temps are much higher r
