If you have had an IUD for a year and are pregnant is it normal to be spotting brown if not removed?

No, it is not normal to be spotting brown if you have had an IUD for a year and it has not been removed. Spotting or bleeding after the first 3-6 months of having an IUD inserted is not a common side effect. If you are experiencing any abnormal bleeding or spotting, it is important to see a healthcare provider as soon as possible to determine the cause and receive appropriate treatment.
