Charting question ... My temps are all over the map even though I take my BBT at the exact same time every day

Mine have been that way too. I found two issues that contributed to my problem.

One, my thermometer - I was using a regular old (fast read) fever thermometer. I think the speed was part of the problem (as though it kind of jumped up a bit, and stopped at the 10 second point). But they are also not designed to be as accurate as BBT thermometers.

Two, my alertness level for the 3 hours prior to temping. I have two young'uns who often wake up in the wee hours of the morning. Due to my hubby's schedule I had been jumping out of bed to get them quieted down before he noticed. If I did this within 3 hours of temping, it was almost always much higher than the day before. Also, if I woke up before the "right" time, I'd often either just lay there, or flop around trying to get back to sleep, and I am pretty sure that altered my temps too.

We have been trying to stop this and let the girls get themselves back to bed this month, and so far, my numbers are MUCH more aligned.

I hope that helps a little. :)

Best of Luck to you!

besides the shown fact that there is an evident shift in my temps once I ovulate my temps do selection from month to month and that i've got not got any set trend in any respect. I even have extremely a protracted luteal section oftentimes lasting 17 days so i would be searching for best temps way previous 18 dpo to verify my being pregnant!

Mine were the excatly the same way!!! it was driving me nuts...they would literally go up and down and uup and down...finally i just kinda quit doing that...and started checking my cervix and i got a saliva microscope...i quit doing the bbt like 3 days before i started ovulating but i still caught it on the saliva microscope and my cm......so i fi was you and that was how your temps were id just go by your cm and maybe trying buying a ovulation microscope...goodluck to you!!

A more reliable and less cumbersome method of charting is now available. It's called Billings Method. I refer you the book: Love & Life (Billings Method of Natural Family Planning) by Leonie McSweeney. If you can't get it I can get it for you on your request. Thanks
