Blood test ?

I had my day 3 blood work done earlier this month and just received the results. I have high Prolactin levels and my dr suggested I see a specialist. I have made an appt with an endocrinologist on the 27th but I of course googled my way to try and find answers. I'm concerned that I can't get pregnant and/or have a tumor on my pituitary gland. Does anyone have any experience with high prolactin levels?
