Hi Flossy,
I had this a few days ago and I called my m/w. She said if it was creamy pink it was nothing to worry about (don't quote me on this being the same for you!).
I've also heard (as has my mum) of some woman who get a pink discharge at their normal time of the month, when they're pregnant. Looking at your ticker it could be what you are having.....and if you look at mine, I think it was what happened to me!
Rest up, get a good nights sleep and call your EPU in the morning if you're still worried!
