Girls, someone had a DHEA sulfate test done, what can I say? I was assigned Dexamethasone 1/4 tablet daily at the clinic, my gynecologist says it's nonsense and this test result means nothing and don't take Dexamethasone, she says everything depends on the length of the uterus. I had a scheduled ultrasound, the uterus is 40mm long, the internal opening is closed, this ultrasound confirmed for me that everything will be fine. Who to listen to and how to act, I don't know...
