What is this???? (TMI photo warning)

I have never seen anything like this....
​I'm on CD11, I normally O on CD14 or 15 - OPKs showing a line but still very negative.
​Anyhow - just wiped and got a clump of really think cloudy snotty stuff, like jelly just before it has set. It had stretch of probably 1 inch.
​I don't get EWCM and this seems far to thick and glupy to be EWCM as it looked fairly hostile to me.
​I haven't BD for 10 days so nothing to do with BD. Just done internal CM check and just white sticky CM.
​Anyone got any ideas??
​Thanks
