As you can imagine, not knowing you or your goals sufficiently, online consultants will not be able to provide you with meaningful advice and/or reassurance. Your plastic surgeon will be in the best position to do so.
Having said that, it is not unusual for patients several weeks out of surgery to be concerned about their breast size ( one way or another). Often, these same patients are very happy several months down the line. Therefore, I would suggest that you continue to be patient, continue to follow-up with your plastic surgeon, and evaluate the end results of the surgery performed 3 to 6 months from now.
Best wishes; hopefully, you will be very pleased with the long-term outcome of the procedure performed.
