Fertile cm ! I need some help y'all ?

Brittany • Christian Mother , & wife ,baby number two Due march 27th??
What is considerd fertile , I know EWCM , but I don't get that now for some reason , my guess is from having a baby and still BF .. But my cycle returned in January . I get every other possible form of cm during my cycle but no EWCM , I'm worried I'm not ovulating :/
