Many fibroids do not cause symptoms. If a fibroid does cause symptoms, it may be because of the size or location of the fibroid.

Symptoms range from mild to severe. Large fibroids can produce symptoms, such as:

    
  • Pelvic pain
  • Low back or leg pain
  • Feeling of pelvic pressure
  • Pain during sex
  • Frequent need to urinate
  • Constipation
  • Bloating
  • Enlarged uterus, giving the appearance of pregnancy
  • Infertility by blocking the fallopian tubes
  • Bleeding symptoms include:

        
  • Heavy menstrual bleeding
  • Clots in your menstrual flow
  • Long periods
  • Bleeding between periods
  • Increased cramping during periods
  • Miscarriage
  • If heavy bleeding continues for a period of time, iron-deficiency anemia may develop. Symptoms of anemia include:

        
  • Weakness
  • Fatigue
  • Shortness of breath
  • Pale skin
  • Lightheadedness
