I have started taking my basal temp at the same time each day. The chart in TCOYF starts at 97, but I’ve been finding that mine are below 97 on some days! What could that mean and how do I chart that? This is my first cycle and I haven’t O’d yet, so i’m assuming it will go up, but why is it so low??

@SaidYES: I chart in TCOYF too and if my temp is lower than 97, my chart will move down into the 96es. I hope that makes sense.

I forgot to answer the second part of your question. I have a low thyroid and high estrogen situation (estrogen dominance often cause low thyroid function). So that is the cause of my low temps. Once I started taking bio-identical progesterone, my temps went up.

hm yeah i see what you’re saying.. I heard low thyroid can cause decreased basal temp.. but i’m wondering if I can be regular thyroid, but still have low basal?
and the chart in the book i have only goes as low as 97.. so i guess that’s why I’m kind of thrown off?

I also have low thyroid and when I was charting, had a few temps lower than 97. I think in TCOYF she just says to scribble them in right below the 97 – that’s why I did, anyway.
I also did some googling and was able to find other charts that started at 96.7 or so. You could look for those, if it’s eaiser for you.

Are you charting to avoid or achieve pregnancy? I think there is a chart on TCOYF to achieve pregnancy with basal temps starting at 96 instead of 97. If you are manually charting, you could just change the numbers, so the first sets are 96s, then it goes up to the 97s (instead of 97s into 98s).
My temps start in the very low 97s, dip down into the 96s before I ovulate, and then go up to the 98s after I ovulate. I just use the regular chart. And when it goes below 97, I simply write the decimal point below the lowest number and do my chart that way. So if my temp is 96.7 one day, I will write “7” below the lowest number on that day. I still connect the lines for each day– but it doesn’t really matter how low it is, because it goes back up on to the chart as I ovulate.
If you are constantly in the low 96s, I would recommend changing the chart for yourself, or finding one that shows 96s so you don’t get confused.

On the TCOYF website, you can download the chart for low temps. Its free. Sorry, I can’t post the link for some reason, but just go to the website, and in the upper right click on Charting your Fertility – Download PDF Charts. The low temp chart goes from 96-98.

It will definitely adjust as you go on. I do mine in celcius but have gone below the default.
If your cycles are regular, I would wait until your next doctor’s appointment to ask for a thyroid test. (Unless you’re TTC and then I recommend a preconception workup.) You can also look up low thryoid function and see if any other symptoms fit.
Good luck with chrating. I’ve had 30+ charts, probably close to 40 now. I have been avoiding, but TTC for one cycle that resulted in my son. 🙂

Mine has gone below 97 as well and I just write it in when it is in the 96’s. I don’t think I have any issues so for what it is worth I attribute it to just having a lower temp that day.
