High Prolactin

Li
Last week I had a blood test to confirm that I ovulated and everything is looking right, and they called yesterday saying I have "abnormally high prolactin levels" and asked that I comeback on Friday for a fasting blood draw. Has anyone else experienced this? From what I have read you can have high prolactin if you are pregnant, or it can be the cause of infertility. I'm a little nervous, and confused.
