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
