Charting BBT - how do you know your coverline temp before Ovulation?

Question

Here is my chart..... http://www.fertilityfriend.com/home/20dca5

I believe I may be ovulating. How do you figure out what your coverline temp is before the chart detects ovulaton?

Thanks xx

The thing with the coverline is that it is not in any way a form of scientific analysis. It's simply a 'visual guide' to give you an idea of what constitutes a rise in temps at Ovulation. Unfortunately, because it is predicated on the rise itself, there is NO way to even 'guestimate' a coverline before the spike has already happened.

I've been charting for 21 cycles, and normally my coverline is between 97.7 and 98.0, but I can never tell where it's going to appear until FF.com adds it on the 3rd day after a confirmed ovulation.
