More common symptoms of uterine fibroids are:

• Abdominal fullness, gas, or constipation
• Bleeding between periods
• Increase in urinary frequency
• Heavy menstrual bleeding (menorrhagia), sometimes with the passage of blood clots
• Menstrual periods that may last longer than normal
• Pelvic cramping or pain with periods
• Sensation of fullness or pressure in lower abdomen
• Pain during intercourse

Note: There are often no symptoms.

A pelvic examination may show an irregularly shaped, lumpy, or enlarged uterus. Frequently, this diagnosis is reliable. In some cases, it is difficult to diagnose fibroids, especially in obese women. Fibroid tumors have been mistaken for:

• Pregnancy
• Ovarian tumors
• Inflammation of the fallopian tubes
• Uterine adenomyosis (a condition in which the uterine lining grows into the muscle wall of the uterus)

A transvaginal ultrasound or pelvic ultrasound may be done to confirm the diagnosis of fibroids. Sometimes, a pelvic MRI is used to confirm the diagnosis.

An endometrial biopsy (biopsy of the uterine lining) or laparoscopy may be needed to rule out cancer.
