Mine were still a milky J as well... Till I hit about 4weeks lol, I'm guessing that I have only boobsploded to a K but havn't been properly checked, all I know is that I have a bugger load of overhang out of even my biggest fitting J cup LMAO! During my pregnancy with DS, I went up two cups, went up another whilst BFing and then one more cup after most of my milk dried up. I had best not end up a damn O by the time this one is off the boob. o.O
