Hi,
Don't worry too much it sounds like a prolactinoma which is a benign tumour on your pituatary gland, I too had levels of prolactin over 1000 and was diagnosed with a prolactinoma 7 years ago, treatment consists of a taking medication which will bring your prolactin levels down and you should be able to conceive. Ask your Dr to refer you to an endocrinologist and they will be able to explain more.

Cheers Jules
