Bbt With A Digital Thermometer HELP

emily - March 29

I have been charting for 2 months now, but my old mercury thermometer broke. So i bought a new digital one as they´re easier to read and quicker. Trouble is, my temps have suddenly gone mad!!!!! I got an ovulation rise and everything but suddenly over the last 4 days i´ve had mad temps varying over .3 degrees up and down. Im due for af in 3 days and normally it´s high until the day of. Is it the thermometer? are the digital ones to be trusted?? Or maybe something else?? PLEASE HELP! Sorry for the length!

Are these the drug store special BBT thermometers which are more accurate? Are you taking your temp before rising in the morning? I wouldn't be worrying about jumps in temperature - just watching with interest. They do talk of an implantation dip, which you might have seen, and then there's the triphasic possibility. Good luck!

Hey thanks. I know about all this and it seemed i´d had a dip. BUT, it went up then went down again. What´s THAT??? It´s not a special bbt one. My mercury one just seemed more consistant! (and blimey my bbs hurt at the mo, lol)

i have a digital ear themometer and it gives readings that vary a bit,my temp is between 35.9- 38celcius. i think they do that.

Emily, I have a digital BBt thermometer that is to the .01 degree and my temp is always all over. I have a differnce of .9 degrees when I am ovulating. I wouldn't worry about it. .3 is nothing. There can be a change of .4 or more when you are ovulating.

Thanks guys. Im not ovulating, im waiting for af. Just seems erratic. My old thermometer put me up to 36.8 after ovulating and with this new one I havent gone over 36.4. This morning 36.1. I dunno!! :)

Now I do... Just started af. Well, checking my cp found slimey brown mucus PLUS the af pains (tmi??) Which gave me a 9 day luteal phase. no wonder I cant get preg!!!

emily- I use a digital bbt as well, and my temps are either regular, or erratic...It's weird! However, it's the only therm. I've ever used! I totally know what you are going through with the 9 day luteal phase- last month (after a m/c) mine was only 6 days- am hoping that changes, but usually they stay the same length. Problem for me is that I didn't chart before I got pg. so don't know what cycle was like before that!
