Two types of CM-EWM & WHITE

Lici
Hi ladies ! Could someone explain this to me: when I checked my CM today: firstly I saw school glue type of CM (white and non sticky) then Egg white mucus (with flecks of white). This is the 2nd time I'm seeing this for the week. GLOW is stating my fertile days are 12th - 18th this month. I BD Sunday morning. THANKS A MILLION!
