Miscarriage and mirena?

Brittany
I have had two chemical/miscarriages. One in April and one this week, both early. 
I had mirena in for about 6 months and had it removed-so many problems with it.
Had it removed October 2014. 
I just wonder if anyone else has had an IUD and had it removed and problems carrying a child now. Did it cause fertility issues? I'm seeing obgyn tomorrow too and am going to ask. I'm hoping it didn't ruin me.
