I had my first mirena iud put in yeaterday. I had some bleeding, which is almost gone now. I do now though have a greyish paper like discharge when I checked for the steings, which are hard to tell but see to already be curling around my cervix. I am still cramping but today up more. I am a smoker and take Toporol, so my ob said this was my safest option. I've had 2 children vaginally. What is this grey stuff and do I need to call the dr?
