charting - overheating question

I've only been charting for this cycle so it's all new to me and have a question.

I woke this morning absolutely boiling hot as my DF had left the heating on all night & I was roasting under the covers. I took my temp and it was 36.4 but when I took it 5 minutes later (after throwing the covers off to cool down) I was 36.1. I've been sitting on 36.1 for a few days and am on CD9.

Should I use the first temp even though I am sure it was caused by the overheating or should I go with the second one? My MB is showing partial ferning so I think I am only just entering my fertile phase which would make the jump in temp this early seem wrong.

Satya, I'd stick with the first temperature anyway.

Charting isn't greatly dependant on an individual temperature, it's about the patterns that appear over time so one temperature that's a little different to the others around it isn't going to change things too much.

If it's just a spike due to the overheating, then your temp should be back to normal the following day.
