I am 31 weeks at the moment and today I have experienced some vaginal "leakage". The discharge is very similar to the normal discharge that you can have between periods, however, I could see a very, very, pale small pink patch in amongst it. That was it. Kept wiping and everything else was clear. Anyone else had experience of this.? Should I be concerned? I don't "feel" that anything is wrong at all, but maybe I'm being too relaxed about it?
