Bratty chart

My bratty chart does not want to behave. My temps are all over the place and ff has not given CH yet. Maybe in the next few days. Background info. I work an erratic schedule of overnights so some of my temps are from sleeping during the day and some are from sleeping during the night. It's never been an issue before. I've been chatting off and on for over 10 years. My last loss was September 2016.
