I'm taking bromocriptine and I'm pregnant but the medicine is making me vomit all the time can I stop taking it and is there any harm on the baby?

Tumor can compress optic nerve, causing loss of peripheral vision of both eyes.High prolactin levels can cause loss of periods & breast milk secretion. U should not use it b/c it will suppress your breast milk production, needed by your newborn. Always consult your obgyn.
