To CM test, or not??

May • Very Happily Married. Wishing for that little one to complete us
I am new to Glow this month and my fertile window has moved around a bit. I am certain it's due to my CM descriptions. The problem I have is that I'm not certain I'm reporting what's going on correctly. Am I best not reporting on CM until I know what I'm really seeing? An inaccurate description in my mind, could cause me to miscalculate my window. Any suggestions please? Thank you
