So, I guess the copper T is an IUD with copper? I would be worried about copper overload. Did your doctor run any blood tests to confirm that. An iron test would be good too. Too much copper and too little iron can cause problems. Why can't you use a barrier method like the diaphragm for birth control??? Low tech and effective. It worked for me all through college and first year of marriage until we forgot to use the thing and the stuff. Turned out to be a blessing as we have a beautiful, healthy 12 year old girl. If we'd waited until we thought we were "ready" we probably would have never had our child. As I was 37 when she was born.
POCS is a symptom of iodine deficiency. If you have fibrocystic breasts, iodine supplementation will get rid of that too. Swanson's vitamins (online) sells 2oz of 2% lugols iodine (combo of iodine and potassium iodide at about 2mg per drop) for about $10. You can get 180 tablets of iodoral (12.5 mg iodine/potassium iodide) online for about $31.
