I am about to start tracking my temp and was reading that if there is a spike of just .4 degrees during you ovulation week then that is when you are ovulating. And remember to take your temp as soon as you wake up don't move around don't even talk before you take you temp and it should be within 30 min of the time you take it every day so if you usually take it at 8am it is okay to take it in the window or 7:30am to 8:30am. Good luck! 🍀 baby dust to you!
