Yes, it is not possible or it is not normal to have bleeding with a post unprotected contact with an IUD in place because IUD as such cannot be the cause for the bleeding at all and one more thing is the delay in the periods for 4 months that can happen in a patient with IUD has to be investigated because the IUD as such is no known to have a delay in your periods at all. So if you have any delay in your periods inspite of having your IUD, you have to meet your gynecologist and you have to find out the cause for the delay in your periods. So the delay in your periods you must also know that it can be due to pregnancy also because inspite of having an IUD. There are chances of having a pregnancy in spite of having an IUD also. That a gynecologist will be able to better diagnose and let you know what you have to do.
