Started having symptoms in the 70's so this was when doctors thought a girl with cramps was just a week little girl. I passed out 30 times per day on the first day of my cycle. Missed a day every month of school if it fell on a week day. I found out 15 years later that it was endo and stage 4. I'm not sure they give it stages anymore. They put me on birth control and it got so much better. Then I went off at the age of 29 and it came back with a vengeance. Passed out on a Sunday morning and missed church. Went to church that night and the preacher prayed for me and wammo it was gone. I am 42 and I have never had a problem with it since. I have had several miscarriages. My pastor died 8 years ago. Anyway, Lugol'sIodine has really helped me with getting my cycle back to a 28 day stretch. I wonder often if this is what I needed all of the time.
