Mouth breathing & BBT

[Mamof1]

I realised my temps seem low and have read this could be through mouth breathing. I have sinus trouble and have done for the last 5 years. I was thinking of taking temp vaginaly next cycle. What Im asking is this is my 1st month charting will this completely ruin my chart and chances of my pin pointing O this month recording my temp with orally taken temps?

Thanks in advance for any replys much appreciated x

No, it wouldn't! Just discard your previous readings (the checkbox there on FF), it will keep the data in case you need it for reference later. Basically you're looking for a thermal shift and 5 days before O is still enough data!
