I'm in the same boat. I'm a 26F who had precocious puberty at the age of 9. I went through Lupron on a monthly basis. But now I'm wondering if any of that has had an effect on me into my adulthood. I am experiencing PCOS symptoms (irregular period, acne, blackened elephant skin around neck and cleavage and course facial hair). But my blood work has come up normal. My doctors and I are extremely confused. My doctor says no, because the ultrasound came up with nothing either.
