TTC and have a prolactinoma

Hi all! I'm 32 years old and my boyfriend and I have been TTC baby #1 for over two years now. Over a year ago we went to a reproductive specialist who found I have a tumor on my pituitary gland causing high levels of prolactin causing me to not ovulate. I've been on meds for it called cabergoline which make me so sick to my stomach and dizzy. I've been off and on the meds as I can not handle the side effects. Right now I am still taking the meds and have been told my prolactin levels are normal so I should get pregnant. Well I'm not and my levels have been normal since May. I'm thinking about stopping the meds again as I truly can not stomach them anymore. Anyone have any luck with cabergoline or any advise on how to handle the side effects? I'm just so frustrated and feeling down about all this. I want to give my boyfriend a child so badly :(
