birth control options

i've had some hormone troubles (hyperprolactinaemia) so had stopped taking birth control, the hormone stuff has got a bit better but i still would like to go back on it, i just don't jnow what the best thing would be that wouldn't change my hormones at all? BC also made me gain weight and get majorly depressed :/

i have spoken to family planning but they don't really know what to do with the situation!
