I don't think I have endometriosis, but I have very painful period. I have a coworker who has endometriosis and we have compared our experiences. From what it sounds like, I have most of the symptoms that she has. For example, we both would spot between periods, we both have to be bed rested on the first day of our period, we're both cold all the time, we both have extremely long cycles (40-50 days), we both have long periods (7-10 days).. I am pretty into nutrition and herbal remedies. I think we both have the same body type and metabolism, which probably makes me a likely candidate for endo in the future.
Recently I found out that vit b complex and along with many other vitamins are important to a woman's hormone and cervix health. 3 months ago I started taking b complex, one a day for women, and calcium. 1 month later, I noticed my period is less painful. And then another month later, my period was shortened to only 5 days. And this month, my cycle has reduced to only 30 days and I experienced absolutely no pain at all.
I've had my problems since I was 13. It never occurred to me that vitamins may help.
Hope this may help. :)
