Pregnant on IUD?

mojen

Has anyone ever been pregnant on the IUD? I am currently on the IUD and lately I've been thinking I've had a stomach bug. It has been 6 days and everytime I eat I feel nauseous or queasy but I am not vomiting or anything. I haven't had a period in about a month or so. I'm going to take test but any stories? Has this happened to anyone?
