When i am ovulating and most fertile (generally 48hrs or so) my CM is an egg white consistency and clear almost like a jelly consistency iykwim- sorry TMI i know. At other times in my cycle my CM has a whiter colour to it and there isnt as much of it so i can generally tell this way. Maybe you dont know what to look for cos you've never paid attention iykwim. Cant hurt to keep an eye out to see if it helps.
GL with the TTC i hope you get your soon
