Prolactin Hormone Issues?

Hey ladies. I was wondering I anyone as had a similar hormone issue and what you did about it. About a year ago, I was 4 months late on my period so I went to he doctor to get my hormones checked. At the time, they said I had high levels of prolactin. My breasts got bigger and I gained about 10 pounds. I was exhausted. My body would essentially go through PMS every month with no period. But, I got my period a week after the blood draw so I didn't think much of it. I lost the weight immediately (within the week) and everything went back to normal. Now I'm back to the same issue. I'm a month late on my period and I am exhausted. I feel like I'm gaining weight. My periods are normally irregular so I am trying to decide if it's worth another $80 blood draw or if I should just wait it out.
