Basal body thermometer

Lindsay • After 9 miscarriages,we got our little miracle in Feb 2016. My little Aidan! Trying now for baby #2!
So I orderedy thermometer online and have been temping the past month. I've been looking at others charts and I think I've been duped. My temp for example would be 36.5, should a basal thermometer be 36.53? Should I have another to the tenth degree?
