I have been on 500mg of PM since Jan 1 with a 13 day break at the first of April.
After starting up again, I noticed the Montgomery all around the perimeter of my Areola too.
My left breast is way ahead of my right, size wise, and it had montgomery all around, and the right just had a few.
I'm hoping the right will catch up soon. Its so nice to have a full bra cup on one side, but sad to have extra space on the other.
