starting to track ovulation

Jacinta
Hello ladies! Went out and bought an obulation digital thermometer today. Going to start tracking and see if i can start to predict when im ovulating 🤗
So. I know i do it first thing in the morning, same time and to not move too much n such before taking temp (i will do it orally)
I know to start on the first day of my cycle. Should be starting REALLY soon. Im actually late (darn AF)  
Any ither tips i should be aware of? Thanks ladies :)
