Patient's own account: I'm 43, and I paid a visit to my doctor because my last few periods were insanely painful. My last periods were 2 weeks ago. I already had three pregnancies that gave me the three lovely children. I did a urine test to check for potential pregnancy, and it came back negative. I started to have my periods at the age of 12, and I have been pretty regular with periods every 28 days for 5 days. I'm sexually active with my husband and I do not have any pain when we have sex. My BMI is 23 and my vitals were normal. The doctor performed a physical exam and found that my uterus was tender and enlarged. She proposed me a hysterectomy and diagnosed me with adenomyosis.
