Love your book!
One thing I would strongly recommend though… I always took my morning temperatures under my armpit and was always discourages as the temps were so low.
A friend recommended under the tongue. I looked through your book and noticed that you recommend either way so I tried it. Well, my temps are consistently 1-1.5 degrees higher! I just think this info needs to be out there so women know it isn’t apples to apples. I was convinced I had thyroid issues when in fact it was just the way I was measuring my temp.
Thank you so much for sharing your research. I will post your observations on my blog.
