Hello all. I just have a question to ask before making a doctors appointment. Im 21 years old, and currently have an 11 month old boy. I got the Mirena IUD inserted in June 2009 and have had no complications with it. I also have not had a period since being on it. The last week or so i have had horrible cramping in my lower stomach, to the point where i cannot walk normal. I also have been gaining weight in my stomach, over the last month or so. I was told that with an iud an at home pregnancy test is not always accurate, i just know its dangerous to be pregnant with an IUD in. I havent gotten my period for almost a year though, so I dont know how to tell if I am. Are these normal things to have with an IUD or should I make an appointment?
