Hello,I have had the Mirena IUD for exactly 5 years now. It is time to get it removed, but I do not have the coverage to do so right now. I have called around to find prices to get the procedure done, but its not likely I could get it done this month. I have seen documentation stating its set to expire in 5 years, but the life expectancy is thought to be 7 years...Is this true? Please note, that its not my intention to keep it in that long, but I just need to know, What are the risks of having the IUD in past its expiration date?
