Symptoms

Sometimes, adenomyosis causes no signs or symptoms or only mild discomfort. However, adenomyosis can cause:

• Heavy or prolonged menstrual bleeding
• Severe cramping or sharp, knifelike pelvic pain during menstruation (dysmenorrhea)
• Chronic pelvic pain
• Painful intercourse (dyspareunia)

Your uterus might get bigger. Although you might not know if your uterus is bigger, you may notice tenderness or pressure in your lower abdomen.

When to see a doctor

If you have prolonged, heavy bleeding or severe cramping during your periods that interferes with your regular activities, make an appointment to see your doctor.
