PMS/depression medicine

So I started taking bupropion (generic wellbutrin) in December and it has done wonders for my depression & overall well being, however I feel like it has made my PMS worse. I used to not really get much PMS at all...maybe just a little emotional and cramps a day or 2 before. Now during PMS I'm way emotional, irritated, almost uncontrollably hormonal....and it all starts a week before. is this normal or does it seem concerning??
