Hi,
​I have never seen anything like this before so wanted to see what you think.... 
​Facts are:
​1) I'm on CD11 and normally O on CD14 or 15
​2) I don't get EWCM, just watery CM around time of O
​3) this appeared on my tissue after a bowel movement
​4) I had not BD for 10 days
​5) it is a really very think, cloudy, glupe of CM which was in a blob and stretched about 1 inch but was so sticky it hung from my finger
​6) CM today is otherwise variable but mainly a mix of clear CM and sticky white CM so think this was a one off 
​Anyone know what this is or why? Should I be worried?
​Thanks ladies
