Elevated prolactin ?!?!

So my OBGYN ordered a bunch of labs and ultrasounds so we can start to narrow down why I am not getting pregnant. She drew my prolactin levels and they were elevated for some reason. She said not by much, but enough to be concerned. She had me fast the night before drawing it again thinking that may bring it down. So I just got a voicemail from her saying it didn't go down the second time, and I needed to call her ASAP. Currently waiting for call back. I'm so scared. All google says is tumors on the pituitary glands as the cause. Has anyone dealt with this before?
