Her2 DCIS and Progesterone

I've had a mast for DCIS which was found to be HER2 but ER-/PR-. (They typed it because they first thought it was IDC. Turned out to be only DCIS.) Anyway, all the cancer drs say NO hormones, even though mine was ER-/PR-. I don't see why I can't continue the natural progesterone I was taking and my Gyn thought they were just being very conservative. She can't overrule them, though. Any experience or studies to look at?
