As if endometriosis weren't bad enough, adenomyosis can show up. How awful. There are advantages to never having had children, and the decreased likelihood of getting this condition is one of them.
This is one of those ties when I might be tempted to just have a hysterectomy and have done with the condition. If I were done having children, I don't know that I would want to "hang on" until menopause, when the symptoms would probably disappear. As long as my ovaries were producing hormones, I wouldn't be in complete menopause-- I just wouldn't have a uterus complicating things.
