I also have this discharge. You may need to get a prostaglandin test done. It would'nt hurt to get your thyroid tested too. My doc ordered these tests for me, which all came back normal, but I still had the discharge. He said it's an imbalance in my hormones, lots of estrogen, but I refuse to use the pill for it. I also have endometriosis because of all the estrogen in my body. I went to se a breast specialist and she said that if the discharge is yellow, whilte or clear, it's normal and nothing to worry about. Only worry if it's pink or red, because of blood. That's when something is terribly wrong. She said most women have this white, yellow, clear dischrage and it's nothing to worry about. I hope this helps.
