Cervical mucus...

I've never really experienced a clumpy CM before (not that I've noticed anyway) - my discharge is always liquid form, but today I wiped after going for a pee and I noticed I had a few clumps of off white CM where I had wiped... 
I'm currently 10dpo - does anyone know what it means? Or have any idea as to what it could be, is it normal? Just I've never noticed (I'm 26 so it seemed odd)
