UPDATE

My doctor called me back today (finally). He said that I was not pregnant, though we both kind of expected that. He said the other labs he took showed that I had high prolactin levels (which I have since found out is kind of this common secret in my family). So, he scheduled me an appointment to see the gyno and he is scheduling me to get an MRI to check to see if I have a (benign) tumor on my pituitary gland. So, at least we've got some answers now!
