Im 20dpo i can tell that my swelling had reduced alot i think its all gone now or enough so that it wouldnt make much difference even if there was a little but left. Im in a 34E at the moment an want to buy a few more bras but dont want to be buying more if they are going to change size again? I havent had any drop an fluff yet so when the bottom fills out more will that usually be enough to go up a cup size? They shouldnt definitely get any smaller i wouldnt have thought. Wanted to be an E but to be honest i definitely thought an E was bigger than what i have got lol so im kind of hoping an praying i go up another size or 2 like i have seen alot of ladies do after drop an fluff, i know some dont but keeping my fingers crossed lol xx
