Prolactin levels?

Hello all 👋🏻

mMy husband and myself have been trying for a baby for 18 months I doctor did some routine blood test and got my results back today they going to refer it to the fertility clinic but just wondering if if any of you ladies had experience slightly high prolactin levels she said they should be between 300 and mine our 500 she said they were borderline they wouldn’t do any unless they were over 600 levels but said it could be down to stress any advice ladies?
