kelly, i don't usually view this but saw your name on a number of posts here and read. here is a possibility.
yes, i had tons of estrogen, measured in the blood, and NO periods. it isn't a good situation, but it turned out to be poly cystic ovaries, where your ovaries produce the ovum, but they don't ripen and cause a period. this is a precursor of type 2 diabetes, and is in fact another autoimmune disease, called insulin resistance. if you are taking preddy, even at different times it can really mess up the insulin levels, which i guess mess up the estrogen levels or something like that. i am trying through diet and meds and exercise to prevent having to take insulin. so far so good.
look up polycystic ovary syndrome. it is common in women, and even more common in those of us with other autoimmune problems.
prayers and peace, s.
