Leigh I have loads of cm, it will be changing colour as it dries most likely. I know it is hard but you need to stop stressing yourself. Someone on here once said, if it is a good pregnancy there is nothing you can do to lose it, if it is a bad one there is nothing you can do to keep it. I know how hard it is, this is my 4th pregnancy after 4 years ttc and we still haven't got any children. You have to believe it will happen and enjoy it as much as you can.
