Thats it, really. Its very, very slight and I only noticed it because I've been prescribed oestrogen pessaries - the applicator (bit like a tampon appicator, but plastic and thinner) came out with a teeny bit of orangey brown mucous on it 
And have had tinged discharge since.
I'm going to gynae on Monday evening, but am a bit freaked out - trying to avoid google, and turning to MN instead! Helpful stories, anyone?
