Sometimes, adenomyosis is silent — causing no signs or symptoms — or only mildly uncomfortable. In other cases, adenomyosis may cause:
- Heavy or prolonged menstrual bleeding
- Severe cramping or sharp, knife-like pelvic pain during menstruation (dysmenorrhea)
- Menstrual cramps that last throughout your period and worsen as you get older
- Pain during intercourse
- Bleeding between periods
- Passing blood clots during your period
Your uterus may double or triple in size. Although you might not know if your uterus is enlarged, you may notice that your lower abdomen seems bigger or feels tender.
When to see a doctor
If you experience any signs or symptoms of adenomyosis, such as prolonged, heavy bleeding during your periods or severe cramping, and they interfere with regular activities, make an appointment to see your doctor.
