question: I have had a Mirena IUD for about a year now and have been having severe lower abdominal pain for about three days now. I am about 5 ft 7 in., and weigh about 150 lbs. I have two children, the youngest being 18 months old, and had an IUD (Mirena) for 3.5 years in between first and second, and never really had this issue. I just want to know if there s any possibility I could be pregnant. I haven t had a period since last month, and don t really have one but three times a year.
