EWCM, or "egg white cervical mucus" is RAW egg-white consistency. Not cooked, poached, boiled, fried... it's raw. (Took me best part of a year to figure that one out.) And the little bugger doesn't show up every cycle - don't stress, you can still conceive without it.

Pretty much every early pregnancy sign can exist with the smallest amount of imagination - wait until your period hasn't shown up before you test and don't think that getting a virus or eating a dodgy bit of fish is a pregnancy sign!
