As above, I'm 39+2 (1st baby) and have tried to keep active-ish in the hope of getting things going.
I've just been for a wee and noticed a considerable amount of clear discharge, a quick google suggests that a mucus plug can appear clear - would anyone know of this is common/likely? I can't say I've had anything similar to this point previously.
I will note that my parter and I did have sex last night but I've obviously washed and showered this morning since so I doubt it could be leftover... you know... but excuse my naivety please!
