ibromyalgia
"I am a 66 year old post-premenopausal female with Fibromyalgia. I was given Amitriptyline to treat my condition. After 6 days on this medication, I began experiencing lower abdominal cramping and on the 7th day, started vaginal bleeding. I immediately stopped the medication, but the bleeding continued for 7 days. After researching, I found that in studies of 854 women, 2 experienced bleeding, both were over 60 years old."
