I just thought I would share my sisters experience, her endometriosis started when she started her periods and she had a hell of a time, in her early 20's she was told that although she was likely to be able to conceive her endometriosis was so bad that any pregnancy would not last. Her endometriosis had got that bad it had even spread to the ligaments connected to her spine. She was offered surgery, which she had and was then given monthly injections to put her into the menopause, she was back packing in Oz for the last 3 months of this treatment and was surprised that once the treatment stopped she still didn't have a period, she was even more surprised when she found out that she was pregnant!! My nephew is now 9 years old and my sisters consultant was pretty surprised to say the least!!
