BBT "cover line"?

Question

Trying to understand my chart- can anyone explain what a cover line is? Thank you!

Answer

I got my cover line halfway through my first month charting when my diphasic shift happened. The cover line helps show the difference in temperature (usually .5-1 degree) before and after ovulation. For example, my before ovulation temps were in the low 97s, but after ovulation, they are up in the high 97s-low 98s. My cover line now shows up at 97.6. Does that help?

Answer

Cynthia this is mine

Answer

I'd like to know too. I've been tracking since November and have never gotten one.
