Hi folks, don't know if anyone can shed any light on this?
I have entered my BBTs on both Fertility Friend and CountdowntoPregnancy this month. One logs them in Celsius, the other in Fahrenheit, just to make things nice and easy! However, I know that the correct temperatures have been logged on both charts.
My question is...on Fertility Friend they have set my coverline temperature at 36.16 (97.088fht). However, on CountdowntoPregnancy, they have set my coverline temperature at 97.5fht (36.38c) - quite a difference really...
Has anyone got any clues as to why this would/could happen when exactly the same temps have been entered?! I'm confused.com!
