I've been tracking AFs & CM and doing OPKs (which may not be as reliable as I thought with PCOS - oops!) as well as keeping a note of anything else (cramps, sexy times, etc.) with Ovia but it's so hard to pin down a possible O that I would really like to start temping - I put it off for ages because it seems hard to get an accurate BBT figure but my DH says he'll just wake me up by sticking the thermometer in my mouth (clean your minds, ladies!) so that might help keep things consistent but I'm concerned that either I'm 'doing it wrong' (is that possible?) or that the my therm is broken because I just did 4 tests one after the other and got: 35.88, 37.03, 35.84 and 36.93 - lots of big differences there!
I know I won't get my BBT in the middle of the day but I can't imagine my temperature is fluctuating that much while I'm sat at my desk? I'm just wondering really if I need to be consistent about where it is (EG under/over tongue, mouth-tightly shut or not...) etc. or if I just need to buy a new thermometer
Would love some advice!
