I don't know about the temps, I didnt' bother to take mine after getting a BFP but I can say that the breast issue is normal. I have days where my breasts are really tender all over and other days where just the nipple is extremely sensitive and tender. They ALWAYS feel super warm though.
my temp ran about the same as you when i was in the first trimester...it's now back to normal and im 24 weeks preg
i mentioned that to my doc and they told me its normal in early preg to have a higher temp
my nips were also the same way...my boobs hurt so bad and i figured out why later on...i went up 4 sizes in 4 months!!!
- is normal to have high teps during pregnancy, also you are supposed to temp when you wake up withought getting up or doing anything if not is going to get much higher.
- some people get tender breast, others just on their nipples, and others non. ( i had almost no tender breast it was much more less than with my period)
good luck and dont stress to much
