TMI but
mine gets very very thick and white after OV, not like lotion but much thicker, i just chart is as creamy. Near OV it gets very very watery so that my knickers even feel kind of wet.. egg white is easy to tell because it gets to stretchy.
the only thing i'm not sure of is what FF means when they say "sticky" havn't figured that one out yet
Whew, glad to know someone else gets both the watery around ovulation and the creamy after!! Mine was SOOO watery this past cycle where I couldn't get any substantial amount on my fingers, but it was just wet wet wet down there. Then, right after ovulation, I got TONs of thick CM... Mine is actually lotiony though.
I am just glad to know that I'm not the only one who doesn't go watery-eggwhite-dry!!
Oh, and I seriously have trouble telling creamy apart from sticky. I usually go with creamy ... I'm not sure there is a super clear distinction between the two, if someone can explain that to me, I'd appreciate it!!!!
As for gathering near the cervix... TMI warning, but if you 'bear down' you can push your cervix closer... I had to learn this when I had to check my IUD strings.
When learning the difference between all the different kinds.. the first thing you want to check is the stretch... try and stretch it between you fingers... because if it won't stretch, its not EWCM... and really thats what you're looking for in the first place, right?

Thats how I started learning and as you can tell, I still don't totally understand the difference between them all but I get by.
