pcos super tender breasts

Lucie
I was recently diagnosed with pcos. My last period ended on the 28th of May. Shortly after my breasts have become crazy tender and sore. They hurt so bad that they can't be touched or even taking a bra off or putting on on hurts. Never felt them like this before. Also they feel "heavier". Whats happening? I'm about 5 days before my next expected period. I'm also irregular.
