Hi and of you who are concerned...I am just turning 21, never had a child before. I got the Mirena inserted when I was 18. And that day they put it in was probably the worst ever. I almost puked. Well, here is 3 years down the road...I've had a few light periods. And now, the past week and a half, I've had continuous medium bleeding...every damn day. Please, please, help. I'm so scared this mirena is going to cause me to become infertile where I'll never be able to have children of my own and then this...help!
