My bra was put on straight after my opp too but yea I would double check, hope it all went well for you and your recovery has been good so far :). I got bought two 32DD sports bras from M&S and found one really comfortable and one really tight and awful even though they were the same size lol, maybe you could try a bigger size for while your swollen as when I wore the one that felt tight I was in a bit of pain whereas the other one I just felt comfortable and supported, my mum wore my spare one to try and stretch it for me lol so you could always try that as well xx
