Help about Cervial mucus

Hi. I'm in my fertile window right now (supposed to be ovulating) but my cervial mucus hasnt changed much other than amount.... Its gotten lighter and heavier and then lighter and now heavier throughout my fertile window but every day it has been white and creamy...(when i do a cm check). Is this a concern or have i just not ovulated yet? Kinda scared that i wont be able to conceive since i miscarried in March....
