Elevated prolactin ?!?!

Colleen

Hello ladies

When for my fertility blood work this week. All my numbers were normal except for Prolactin. They were slightly elevated they said. 23.1 (telling me the range is 2-18.5) they told me to retest and make sure I fast this time. They told me if it doesn’t go down I will need to go see and endocrinologist. What does this mean and what can it effect?
