Tilted uterus or retroflexed uterus symptoms include painful sex and the most pain when in the "on-top" sexual position, along with painful periods. Back pain, discomfort when using a tampon and a predisposition to urinary tract infections are other signs that you might have a tipped uterus. A doctor should be able to tell you during a routine pap smear. Uterine fibroids, non-cancerous tumor like growths inside the uterus, can make the uterus more susceptible to tipping, but most people are just born that way. A retroflexed uterus is tilted toward the back.
