Swollen breasts and tummy

Hi I'm new here and wondering if anyone can help.
I was finally diagnosed with PCOS last year. I am really struggling at the moment with a very swollen tummy and swollen breasts (the left one in particular looks like I've stuck a balloon up my top?) It doesn't seem to matter what stage in my cycle I'm at. One day my clothes will fit, the next I can't button things up, it's really noticeable. this has gone on for ages and I'm so fed up , it's so uncomfortable (but not sore) and i just feel fat and horrible (I'm a size 12 so wouldn't normally be bothered)
I'm not on any meds as I'm really worried about my fertility and my doc said it was prob best to let my body be just now , is there anything I can do to stop this?
