Symptoms of an IUD pregnancy. A pregnancy with an IUD in place typically has the same symptoms as any regular pregnancy -- including breast tenderness, nausea, and fatigue -- so if you're experiencing those symptoms and you have missed your period, call your doctor right away to find out if you're pregnant.
1 Other possible symptoms of early pregnancy include mood changes, increased urination, headaches, low backache, breast tenderness, darkened areolas, fatigue, nausea, and implantation bleeding. 2  Symptoms of late pregnancy can include leg swelling, backache, heartburn, leakage of urine, and shortness of breath.
