You should be able to safely remove it whenever you want. There are some that last up to 5 years, but that doesn't necessarily mean that you can't remove it for that long. The point of an IUD is that you can have safe, non-permanent contraception for as long as you choose.
If you leave the copper IUD in too long, there are no potential health problems. If you leave a hormonal IUD like Mirena in too long, you may not be protected against pregnancy, but there are no other risks.
You should remove your IUD if you want to get pregnant, if you are pregnant, or if its useful life is expired and it's time to replace it.
There is no need to remove the IUD before (or after) having your tubes tied. Leaving it in will ensure continuous protection.
You should never remove your own IUD. You should seek a doctor immediately to test to see if you are pregnant and have your IUD or a new IUD inserted. Removal of an IUD can almost immediately leave you prone to pregnancy.
It's the same as the procedure to remove the IUD when you're not pregnant.
You should get the IUD removed if you are seeking pregnancy, or if it is at the end of its useful life.
There's no special time to remove the IUD if you want to get pregnant
i have an iud for over 30 years i had an ultisound and they found it the string was not there
There are no health consequences to leaving the IUD in longer than five years, but a hormonal IUD may not be effective past its useful life span.
Missing a period once in five years is normal with or without the IUD.
The only danger of an expired IUD is pregnancy.
The Mirena IUD lasts five years, Paragard lasts 12, and Skyla lasts three years.
