I was on the Mirena for 2yrs. , I was told that when i wanted it removed i would be able to get pregnant quickly. But I haven't we have been trying now for 3 yrs. and nothing! As i ws doing researching about the Mirena, I later found out that it could cause sterilization in the tubes. I was devastated, We new we could have children because we have girls n 1 son. I truly believe that the Mirena has caused me damaged to me not being able to concieve again. Please do more research when dealing with all birth controls, mainly the mirena.
