Hi lynros,

I chart my temps too, although this month I have only charted until 4 DPO - I am getting a bit over it all and I find that I sleep not so well when I am charting. I hardly ever get temps of 37, and never got even close to it the cycle I fell preg, so I don't know about that theory either. LMK if you would like to see my preg chart - I can post a link to it if you like. Anyway, as far as I am aware, the theory with the temps is that if they stay elevated for longer than your normal luteal phase then you *may* be preg - that's what happened with mine and as it turned out I was preg.

HTH
