2WPO is quite early for conclusions. Maybe wait 1-3 weeks and then set up a follow-up appointment with your Doc, if the issue persists. Also I don’t know your bwd but according to your height weight and frame it seems like 320cc mode+ profile diameter should fit you fine, unless if you had small bwd and you went with mode+ 320cc and pushed the limits of your breast diameter, then I would worry. But I’m not a doctor, just trying to help you.
By the way the results look great!
